Steep meadows before the summit of Timber Peak

Overview:

The South Baldy Trail #11 ascends from a darkling canyon bed up to the sunny ridgeline of the Magdalena Mountains. Access is easy and the grade is moderate. The subsequent views from the Timber Peak Trail #70 sweep the region; from the San Juans in southern Colorado to the Black Range in southern New Mexico. Pick a clear day and go! Novice hikers should know that snow sometimes obscures the trail. If you have doubts about your navigation skill then come anyway, bringing a resolute willingness to turn back when the tread becomes doubtful.

Driving Directions

  • Drive to Socorro, NM on Interstate-25 (I-25)
    • If you are coming from the north (e.g. from Albuquerque) 
      • Take Exit 150 from I-25.
      • After 0.4 miles on the off ramp, at the stop light on the ramp end, go straight ahead onto California Street.
      • After 1.3 miles on California St, at a stoplight, go right onto Spring St.
    • If you are coming from the south (e.g. from Las Cruces)
      • Take Exit 147 from I-25.
      • After 0.7 miles the ramp “invisibly” segues onto California Street, reset your odometer as you go past the first gas station.
      • After 0.6 miles on California St, at a stop light, turn left onto Spring Street.
  • After 0.6 miles on Spring St, at the first stop sign, go left onto US-60 West (signed).
  • After 14.9 miles on US-60 West turn left onto Water Canyon Road. Just before the turn you will see a sign on US-60 saying, “Water Canyon Campground”. There is a state historic marker at the junction as well. 
  • After 4.6 miles on Water Canyon Road, at the Water Canyon Campground (signed), turn left onto Forest Road 235 (signed, roadbed becomes gravel)
  • After 2.1 miles on Forest Road 235, at a wide and level spot on the right side of the road, park at the trailhead. A sign for  “South Baldy Trail No. 11” should be visible. (FR-235 is numbered with small, blue signs about every tenth of a mile, the trailhead is about 100 yards past the blue sign saying “24” and a second sign saying “ELEV 7500 FT”).

A sign at the start of FR-235 recommends against driving the road unless you have a high-suspension, 4-wheel drive vehicle. For now, however, almost any normal passenger car can make it as far as the trailhead.

Trailhead:

A wide spot on the right side of the road, tucked into the floor of Water Canyon, forms your trailhead. On this date there was some water moving in the canyon, but you should not count on it as a resource. There are no services at the trailhead, although you will pass several campgrounds along FR-235 that have vault toilets. Water Canyon Campground is currently open and you can check on its status here. Important note! About 100 yards before this trailhead there is another trailhead, signed for “South Canyon Trail No. 15”. That is a separate trailhead for a separate trail! 

Data:

  • starting elevation: 7,540
  • ending elevation: 10,510
  • net elevation: 2970
  • distance: 4.3 miles (one way)

Hike Description:

Warm morning sunlight strikes the canyon rim.

At 7500 feet you might expect juniper and pinyon pine, yet this cool canyon shelters a narrow forest of tall and thriving pines. Some have the cinnamon bark of ponderosa pine, but others had a dark gray, vertically furrowed bark typical of a Chihuahua white pine. Recent snowfall has toppled some of the old snags. True to Murphy, these always seem to fall directly across the tread. Dodge those trunks and hike on – all such impediments fade away in less than a half mile. 

South facing wall of Water Canyon

December mornings refrigerate the canyon bottom. Fortunately, the trail departs the canyon bed at 0.8 miles. A long switchback pulls you onto the south-facing wall of the northern-most tributary to Water Canyon. Climb into morning sunshine and feel it going to work! Off come the wool hats and puffy coats. At the switchback’s end the trail turns up-canyon and begins a carefully engineered slog that slowly creeps up the wall – almost reaching the rim. At some point you may want to dash up onto the rim for a fine view down into Copper Canyon and across the east-facing slopes of the Magdalenas.

Snow covered trail

Below you the tributary bottom starts to soar and at 1.9 miles the bed rises to meet the trail. Here, on this date, snow began covering the trail. Those with little navigation experience should recognize this turn-back signal. For others, follow the trail as it crosses the tributary and turns southeast, traversing into the large bowl encompassing the canyon’s headwaters. The trail slaloms between the forested hillocks that dominate the ridgeline. You may hear some traffic noise – the main ridgeline houses both the Magdalena Ridge Observatory (MRO) and the Langmuir Laboratory. At 2.9 miles the South Baldy Trail ends at its upper junction with Forest Road 235.

Sign at trail’s intersection with FR-235

If you were to turn right and follow the road uphill you would come to South Baldy, the highest peak in the Magdalenas. For this route, however, turn left and follow the road as it gently descends a quarter mile. Find the heavily weathered sign for Timber Peak Trail #70 at a traffic turnout. (Curiously, the turnout had been plowed – possibly to make room for later snow accumulations). Depart the road and follow the tread up the ridgeline.

South Baldy Peak (MRO is midway across the ridge’s snow field)

A series of bumps populates this ridge. The trail makes several westerly-detours to contour below them. The views are terrific. Above and west of you lies the summit of South Baldy, snow clad in winter and grassland in summer. The MRO is a prominent, white, ridge-top building capped with a shiny aluminum dome. Below and east of you lies the Socorro Mountains. Straight ahead (south) lie views into the depths of Sawmill Canyon. At 3.8 miles the tread rejoins to the ridgeline and barrels straight at Timber Peak.

San Juans (snow capped, left-third on the horizon) and Ladron Peak (right-third, middle distance)

Snowy conditions can make that ascent demanding. Postholing at altitude! A broad meadow graces the flanks of the summit block and it is pitched steeply enough to require kicking steps into the snow. The grade finally gentles and you are guided into a small alcove framed by fir trees. You might think that you’ve arrived. False hope! The true summit lies 20 or so feet above you. This is not technical terrain, but you may have to probe the snow with your boots to find adequate foothold. Finally, at 4.3 miles from the trailhead, join the weather-station sensors crowning this summit.

View over Sawmill Canyon to Hardy Ridge, San Mateo Mts and (visible just above San Mateos) the distant Black Range.

Views include the snow clad San Juan Mountains directly north, Ladron Peak to the northwest, along with hazy views of the Sandia Mountains and Manzano Peak in the Manzano Mountains. To the southwest lie the Oscura Mountains and the rounded dome of Carrizo Peak. Look west, over the vast gulf of Sawmill Canyon, to find San Mateo Peak in the San Mateo Mountains. Beyond the San Mateos (in the far distance) glimpse the north end of the Black Range.

Author, obscuring your view of the Oscura Mountains

Postholing became a problem above 9500 feet. In preparation, I brought along my elderly MSR snowshoes but failed to examine them closely. Alas! The ancient elastomers that made up the straps had quietly succumbed to old age. I had gone no further than 20 feet when the bootstrap on the left shoe broke. The right shoe straps broke about 100 yards later. Fortunately, it was rare to plunge more than a foot or so. If you have functioning snowshoes take them with you in the car. As you approach on US-60 take a look at the summit of South Baldy. If you can see snow up there then you will want to carry your snowshoes into the upper reaches.

I didn’t carry an ice ax. There was no need for the South Baldy Trail. The Timber Peak Trail has several segments of side-hilling on steep meadows where an ax might be advisable.

On a cool day I went through just one liter of water. I was glad to have two, however, as the sun in the afternoon shone warmly on the west-facing slopes and water breaks were frequent.

Kicking steps at 10,000 feet is hard work. Has your party just come from sea level? Then keep an eye out for signs of acute mountain sickness.

Solphoto has a writeup and nice photos of the tremendous views you get from the ridge leading to Timber Peak. Check it for what this part of the hike might be like in warm weather.

The Chamber of Commerce in Magdalena, NM has an extensive description (PDF) of nearby trails including the South Baldy Trail and the Timber Peak Trail. Bookmark it if you need route suggestions for hiking in this area.

The HikeArizona site, a great resource, provides a brief description of a variation which you’d hike up the South Baldy Trail No. 11 all the way to South Baldy Peak.

In milder weather folks with high-clearance vehicles drive to the Timber Peak trailhead and do just the upper part of this route. George at Ondafringe has a description with numerous photos to give you an excellent idea of what to expect in warmer seasons, extending the trip to an open part of the ridge beyond Timber Peak.

A post at the New Mexico Volunteers for the Outdoors explains how it is that the South Baldy Trail is in such excellent shape. Thanks to Nick T and all the other volunteers!

Sheer canyon walls and level wash

Overview:

A feast of iconic western imagery, Potato Canyon proffers sheer canyon walls, gigantic trees, wildlife, a brief slot canyon and easy hiking into the heart of the lonesome Withington Wilderness. In the hike’s uppermost reaches (barely touched in this route description) there is evidence of a recent fire. This route would be a national treasure were it not for the last six miles of the drive. Those miles are hostile. Hikers possessing a high clearance vehicle and a high tolerance for care-filled driving should pack packs and go.

Driving Directions:

True!

Stretches of this drive are ugly. A high-suspension, four-wheel drive vehicle is required (alas). In its steeper sections the forest road slaloms between boulders and quakes under extended piles of loose rock.

It is a shame because the hike up to the waterfall is as family-friendly as any hike in New Mexico.


  • Drive to Socorro, NM on Interstate-25 (I-25)
  • If you are coming from the north (e.g. from Albuquerque) 
    • Take Exit 150 from I-25.
    • After 0.4 miles on the off ramp, at the stop light on the ramp end, go straight ahead onto California Street.
    • After 1.3 miles on California St, at a stoplight, go right onto Spring St.
  • If you are coming from the south (e.g. from Las Cruces)
    • Take Exit 147 from I-25.
    • After 0.7 miles the ramp “invisibly” segues onto California Street, reset your odometer as you go past the first gas station.
    • After 0.6 miles on California St, at a stop light, turn left onto Spring Street.
  • After 0.6 miles on Spring St, at the first stop sign, go left onto US-60 (well signed).
  • After 26.4 miles on US-60, at the far end of the town of Magdelana, turn left onto NM-107 South (well signed).
    • NM-107 is paved for the first 4.3 miles, then turns to gravel. The current roadbed is in exceptionally good shape.
  • After 16.8 miles on NM-107 turn right onto Forest Road 52 (FR-52).
    • FR-52 is very rough. High clearance vehicles only. The Subaru made it, but at the cost of abuse to the suspension and tires.
    • The junction is well signed.
  • After 3.3 miles on FR-52 turn left onto FR-56
    • FR-56 is signed “Not fit for passenger cars“. This is correct.
    • The junction is well signed.
  • After 2.7 miles on FR-56 pull out onto the two-track going up Potato Canyon.
    • FR-56 drops into Big Rosa Canyon and stays there. This could be an exceptionally poor choice of parking during monsoon season.
    • At 2.1 miles the road enters the main canyon wash and the roadbed becomes significantly better!
    • The Potato Canyon trailhead is signed (see below), although the sign is getting shot-up.

Trailhead:

The Subaru in its native heath

The trailhead is a flat spot beside a two-track going up Potato Canyon. Don’t leave your vehicle on the two-track. On this date there were ATV tire tracks in the canyon bed for the first half-mile. Clearly, people do drive here. There is a shot-up sign saying, “Potato Tr”. There is no water, toilet, or trash service at the trailhead.

Data:

On this date I used a new GPS, which gathered only 44 data points. My old GPS would have collected more than 1000. Know that the track does not reflect the twists in the canyon, so distances are likely to be underestimated.

  • lowest point: 6706 feet
  • highest point: 8728 feet
  • net elevation: 2020 feet
  • distance: 5.7 miles (one way, may be understated)

Hike Description:

Depart Big Rosa Canyon by hiking the two-track west into Potato Canyon. The two-track gets lost amidst small waves of gregarious boulders and a web of gullies. The terrain is not bad for hiking, but a battering to wheeled vehicles. The canyon has the feel of a movie-set; a dry land of lonesome ponderosa, ancient alligator juniper, layered sandstone, numerous deer tracks and vertical canyon walls. The broad wash writhes, yet the footing is usually so good you can afford to stare at your surroundings. 

Early view into Potato Canyon

In a quarter mile, just past a sign for the Withington Wilderness, enter the first deep section of the canyon. Here the waters have cut down through a tall intrusion of hard rock. The south side of the canyon is a wall of this rock, but the north is far less steep; grassy and sunlight even in the early morning of a late fall day. Rather chilly (early in the morning) but the shaded nature of this hike is one of its biggest attractions. 

Foot thick gray oak

Inside the canyon there is an unexpected mixture of trees. Ponderosa pines have crept down this cool and moist environment, oddly competing with alligator juniper for the canyon’s resources. Many trees are outsized. Gray oak, for example, is typically encountered as brush. In this sun protected bottom, however, one old Gray flaunted a foot-thick bole armored with bark as corrugated as the bark of a Douglas fir. Similarly outsized Gambel oaks and big pinyon pines are everywhere. Amazing.

Western iconography

The first navigation challenge comes at 1.7 miles, in the junction of two canyons. The confluence bed is quite broad, flat and densely forested. You may need to scout around, but take the fork going southwest, not the very-prominent fork heading north of west. (That is, stay to your left, heading uphill). On this date a pretty run of water surfaced in mid-wash just west of this junction. Tracks show that turkey, deer and a cat (likely a bobcat) use this watering hole.  

Deadfall

Hiking on a sandy tread can blow out your calves. It is much more stressful than walking a regular trail of similar grade. Grit creeps into your boots. Even with gaiters you may need to stop now and then for a break to clear the those insoles. Deadfall crosses the wash, wherever running waters have undercut a tree. (In these cases you can often get around the barrier by walking past the rootball, the fall usually pulls the rootball from the bank). Some of these fallen trees make excellent benches.

Waterfall (path is to right)

At 4.0 miles the bed of the canyon rockets skywards and water sluices down its face. In early November the shadowed walls of this box can be decorated with ice. The waterfall is a navigation puzzle – look to the north side (to your right looking upstream) for the path forward. The last few steps of this path are right at the edge of the waterfall and somewhat exposed. For acrophobes it may be best to have lunch at the base of the falls and return. Others should continue on. There is a short but terrific little slot canyon immediately above the waterfall.  

Short slot Canyon

Above the slot canyon the wide wash regains control. At 4.3 miles come to the another navigational issue at a confluence of canyons. A wide, smooth wash sweeps into the junction from the southerly branch (to your left), very tempting! A much more jumbled wash comes in from the northerly branch and ends atop a three foot embankment, forming a “hanging wash”. Go northerly, clambering onto the hanging wash and continuing uphill.

Middle finger rock

This mellow beach stroll continues onward and at 5.2 miles swings due west to open up views of Mt Withington. So close! Here the grade begins to increase significantly. Scan the northern bank (on your right while ascending) for cairns that lead you steeply up into the northerly branch of the next junction. Almost immediately above this junction the trail takes a four-foot vertical leap straight up off of the canyon floor and onto the terrain that separates the two branches. The ground directly above this “leap” is only slightly less than vertical. Imagine rock-climbing, but on marginally consolidated soil. Turning back before the leap would have been the reasonable thing to do. Without making any recommendation, it is possible but exposed to climb from tree to tree until reasonable “footing” reappears. On the narrow strip of land between the canyon branches continue on the steep climb. The tread, submerged under blackened debris, dodges between roasted tree trunks. A cluster of stone pillars topped by “middle finger rock” appears. Is that a sign? Have something to eat, think over your options, and if retreat seems good then return the way you came.

(Note: for those aiming at the summit of Mount Withington, keep an eye out for a fork in the trail that appears before you encounter that rude rock. This fork is obscured by a huge old log that has fallen into the tread in three, large and rotting chunks. One fork of the trail goes down to the “southerly” canyon branch – left on ascent – and that may be the best way forward).

Recommendations:

Go.

Don’t go if there is rain in the forecast. The bottom of Big Rosa Canyon (part of the approach drive) is said to be subject to flash flooding. The slot canyon is short, but for a slot canyon it is unusually awkward to negotiate.

Wear gaiters to keep sand out of your shoes.

Check your vehicle’s spare tire and jack before going. Have spare water and warm backup clothing in the vehicle. The Withington really is wilderness.

The remoteness of this hike makes extra care worthwhile. If you’ve been lightening your pack by sacrificing some optional medical supplies you may want to temporarily restore them.

Links:

A rock climbing site explains that Potato Canyon is named for The Great Potato rock formation found on the San Mateo ridgeline, high above the canyon. The photos are great.

A. Jackson Frishman has done an excellent job of capturing the feel of Potato Canyon at the FrishmanPhoto site. Scroll down to the second photograph.

Similarly, the writeup at DoughScottArt has a terrific photo of the waterfall, which gets named as the “Pink Cascade”. The text cautions that the Cascade disappears during the dry seasons, and a very clear map indicates exactly where to expect to find the cascade.

At the Wilderness 50 Challenge site the author makes some pointed remarks about the inadvisability of taking a sedan into the Wilderness (based on actual experience).

There is a thoughtful writeup of this trail (PDF, scroll to page 35) from the Forest Service. They give a pretty detailed description and caution, as mentioned above, that water does not always flow in the canyon. It is surprising to see this trail given a “most difficult” rating, but they explain that the primitive condition of the tread and the remoteness of the area serve to weight the decision.

A writeup in the Albuquerque Journal suggests that passenger vehicles can make this drive, despite the signs suggesting otherwise. Please note that this writeup comes from 1999!

The NMTrails website includes a trip report from 2017. The author notes the difficulty of finding the trail once you enter the old burn, and the stark incisions made into the flanks of Mount Withington by flooding after the fire.

Peñasco Blanco

Overview:

Roughly 1200 years ago the Ancestral Puebloans raised monumental rock structures along Chaco Wash. This hike follows the Wash past several enormous structures, turns back at the Peñasco Blanco ruin and finishes by ascending a narrow cleft to a pair of the high pueblos. Go! There is no better way of introducing newcomers to hiking in the desert southwest.

Driving Directions:

  • From I-25 near Bernalillo (just north of Albuquerque) take exit 142 for US-550 North.
  • At the end of the ramp turn onto the north-bound lanes of US-550. If you are coming from the south then the ramp will be 0.2 miles long and you will want to follow it as it follows an extensive bend to the driver’s left.
  • After 112.6 miles on US-550, after a National Park sign for Chaco Canyon Culture Nation Park and after mile marker 112, turn left onto Indian Service Road 7061. There is no sign naming this road, but about 100 feet down the road is a large NP sign for Chaco Canyon National Historic Park.
  • After 5.0 miles on ISR 7061 turn right onto County Road 7950 (signed). This road is initially paved, but turns to gravel in 2.9 miles.
  • After 12.4 on CR 7950 miles veer sharply left onto CR-7900 (not signed). The turn is obvious – there is a “straight ahead” option but that alternative sees very much less traffic.
  • After 5.8 miles on CR7950 (which becomes paved as you enter the park) come to the Vistor’s Center. Registration is required, see below, so stop in. On exiting turn right to continue on the Park’s Loop Road. You will pass several ancient pueblos on the Loop Road and each is worth a substantial visit.
  • After 3.4 miles on the Loop Road come to a junction where an extension road (not named) continues straight down the wash towards the trailhead. (The Loop Road goes left at the junction). Go straight ahead. Note: there is a parking lot just before this junction for the Pueblo Bonito and Chetro Ketl complexes. Both are amazing.
  • After 0.4 miles, in the parking lot at end of the extension, park your car.
Sign at start of ISR 7061

It is also possible to come into Chaco Canyon from the south, on NM-57. On this date I drove that way while leaving the park and the experience cannot be recommended. It was perfectly passable for high-clearance vehicles but it is a dusty, bumpy, long, slow drive. Deep ruts could be found mid-road in all the low spots, frequently accompanied by tall piles of displaced dirt. A low-slung sedan would not be happy with this experience. There are numerous cattle guards in the road. Sometimes the initial ridge on the cattle guard can be exposed several inches above the roadbed. It is tire hell. Definitely stay away from NM-57 if the conditions are wet.

Trailhead:

Rutwo below the north canyon wall

A park fee is charged at the Visitor’s Center. Each car is $25. If you come in by some other means then it is $15 per person. National Park and military passes are accepted in lieu of payment. Ranger guided tours are available. I briefly overlapped with a guided group and it seems like a good option. The restrooms are currently closed although port-a-potties are available. There are trash receptacles. There is quite a museum and drinking water is said to be available in the Visitors Center.

At the trailhead you might want to leave your pack in the car and go get the paperwork out of the trail register. The paperwork records the date on which you start your hike and the make and model of your car. This paperwork just gives the rangers an edge at finding the lost hikers. You will need to return to your car to leave part of the registration ticket on your dashboard. Now pick up your pack and off you go!

Data:

The altitude gained and lost is small, although acrophobes may want to stay off the steep climb up to Pueblo Alto.

Distance: 10.8 miles

Hike Description:

Follow the broad gravel road as it heads northwest, past the trail register. A relatively small ruin know as Kin Kletso (Yellow House) is well-preserved and very much worth exploring. This construction makes use of relatively large and uniform sandstone blocks that resemble bricks. Evidently this style of construction arose later than the style found in other complexes such as Chetro Ketl. Behind the ruins a trail leads steeply onto the canyon rim, as described below.

Casa Chiquita

The roadbed bends sharply into a side canyon but swings right back, reaching Casa Chiquita in1.2 miles. The centuries have been less kind to the “Small House” (although it anything still standing after 1000 years gets good marks for ruggedness). With 50 rectangular rooms and two large round-rooms it tells a story of enormous public commitment, even while distaining to name what aroused that commitment. It is reported that this ruin has not been excavated, so some of the rooms hide beneath wind-deposited sand and silt.

At this point the road narrows into a single track, but one that obviously receives a great deal of expert care and attention. You won’t get lost. At 1.7 miles take a fork to the right (signed as Petroglyph Trail) to follow a side loop that keeps close to the north-eastern canyon wall. At scattered points along the wall the ancestral puebloans pecked images and geometric shapes that have survived the ensuing millennium. Spirals are a very common motif, although it is not obvious what this meant to the artists. The Una Vida trail (near the Visitor’s Center) has at least one glyph depicting a person holding a spiral like a shield.

This is parched terrain. Four-wing saltbush, apache plume, and claret cactus all dwell here, competing for water but not for sunlight. Signs warn of the danger where the trail crosses the Wash bottom. That is probably true, but on this date the key element (water) just wasn’t present. Looking further down canyon (northwest) you will see a wall. This is not a dam, but rather the confluence where the Chaco Wash joins the Chaco River. At 3.2 miles come to a puzzling sign saying “Supernova Pictograph”. Look directly above the sign for rock art showing a hand, a moon, and an image often interpreted as the supernova of 1054 (bright enough to remain visible during the day for 23 days)

Once-Oculated Rock

The trail gently switchbacks up onto the southwest rim of the canyon, bringing you to the site of the Peñasco Blanco complex at 4.1 miles. This site, like Casa Chiquita seems to be preserved for future excavation. The visible walls, unprotected by the canyon, have taken a beating by frost and sun. The remaining walls show extraordinary artfulness, with alternating rows of larger and smaller rock panels. Evidently this work was either meant for the amusement of wall-builders or as offerings to the supernatural since these rocks were usually covered with adobe and hidden from sight.

Pueblo Bonito

Return the way you came. Energetic hikers can then take the trail leading from behind the Kin Kietso site to the northeast rim. The tread leaps up the northeast wall, using a cleft behind a fin of rock to bring you to the top. From the rim you have many options, including a spectacular overlook of Pueblo Bonito and a loop trail that will take you past the Pueblo Alto complex.

Recommendations:

Standard desert hiking advice holds, including:

  • Your car can fail out here. Bring gear. You want to have extra clothing (adequate for waiting out a cold night), extra water in the car, jumper cables, a well-greased jack and an inflated spare tire. Check your gear before leaving home.
  • There might be a cell tower in the park, but that is line-of-sight transmission and there are long miles in the surrounding canyon land where you will have no cell coverage. As always, it is a good idea to have someone outside of your hiking group who knows your travel and hiking itinerary.
  • There are long stretches of trail where there is no protection from the sun. Even in October that can be draining. Water, sunscreen, sunglasses are necessities. If you have a larger group then it would be a great idea to have a couple umbrellas to provide shade if someone gets too roasted.
Pueblo Bonito door frames

The park’s campground is very popular and currently is offered on a first-come, first-served basis. If you do want to camp then you will also want to come with backup plans.

The Hiking and Walking site has a nice description of the Peñasco Blanco hike, which includes a chart of elevation change (and obligatory warnings about the quality of the roadbed leading into the park!).

The folks at Explore New Mexico give the loop route to Pueblo Alto a big thumbs up. Their post includes some photos of people ascending up the slot that leads to the rim of the canyon.

Taos News also has a writeup, which includes some of the history and a warning about the changeable weather in the desert.

There is a detailed description of this hike at the Hiking Arizona site (a great general resource for southwest hiking).
