01 Jack's Peak
View past pines to summit of Jack’s Peak

Overview:

The Jack’s Peak Trail is an out-and-back expedition into the Burro Mountains of southern New Mexico. It is easy to access, it is fun to hike, it crosses two significant life zones, it offers a great morning’s exercise (well within the ability of most hikers), and provides views all the way to the the distant mountains of northern Mexico. Jack’s crown of antennae diminishes the Peak’s claim to wilderness, but those of us who carry cell phones into these mountains cannot complain too much about that. Frankly, it seems unlikely that people will travel from Albuquerque or Tuscon just just to hike this particular trail. For folks who live in the Silver City – Las Cruces – Lordsburg area, however, this destination offers a sovereign cure for the perils of cabin fever. 

Driving Directions:

03 kiosk at start of trail
Trailhead kiosk
  • From Silver City, at the junction of US-180 and NM-90 (signed as Silver Heights Blvd and N. Hudson Road within the City), go south on NM-90.
  • After 21.4 miles on NM-90, past a sign saying “Continental Divide Trail”, turn right onto Forest Road 4090-O (turns to gravel).  You’ll find the sign and the turn just past mile marker 22. 
  • After 0.3 miles on FR 4090-O, at the far end of a closed loop in the road, park at the trailhead. The trailhead is marked by a kiosk saying “Jack’s Peak – CDNST Trailhead”

FR 4090-O is rutted. It is perfectly passible in a sedan but a little caution is advised.

If you are driving north on NM-90 out of Lordsburg you will go past mile marker 21 (it’s there, I checked). Then you will drive over a small hill with a sign saying “Continental Divide 6355 feet”. Near the bottom of the hill there is another sign saying “Continental Divide Trail” after which you’ll find the left turn onto 4090-O.

Trailhead:

02 The Mighty Camry at Jack's Pk trailhead

The trailhead is simply a wide spot along FR 4090-O. There are no toilets, water or trash recepticals. Indeed, a sign on the kiosk marking the trailhead pleads with visitors to pack out any garbage they bring in with them. It seems that visitors do pay attention. There was little litter along the trail. The loop at the end of FR 4090-O brings you through a large and very attractive meadow. Even in the chilly month of October it was home to several RVs and campers.

Hike Description:

04 Broad height of land above trailhead
This height of land obscures the view to Jack’s Peak

From the kiosk head north in sandy, juniper-shaded terrain.  Ahead of you is a broad and steep height-of-land that prevents you from seeing the summit of Jack’s Peak. In about a quarter mile the trail comes to the foot of this steep landscape and swings to the west, preferring a long ascending contour rather than a direct assault. Soon, however the land is slashed north-to-south by Whitetail Canyon. Here the trail turns up-canyon, clinging to the upper reaches of the canyon walls. This is Upper Sonoran terrain. The cholla and prickly pear cacti compete with with banana yucca and mountain mahogany. It is surprising to learn, from Julyan’s valuable The Mountains Of New Mexico, that the core of the Burro Mountains is igneous. The fist-sized talus under your feet has the pale coloration and granularity of sandstone. Perhaps these are the remains from the sedimentary layer that suffered the igneous intrusion. 

06 Yellow Cliff

Eventually the trail clambers up onto the canyon rim just above a knoll, which makes a good landmark for your return trip. Whitetail Canyon remains on your left while an unnamed drainage falls sharply off on your right,  leaving you atop a rib. Follow this rib as it ascends, “staircase style”, with steep passages over softer rock alternating with relatively level passages on the hard stuff. After four or five of these steps you will note that the trail is heading directly toward a high ridge fronted by yellowish cliff. Pinyon pine becomes more dominant. Suddenly the trail comes to an unexpected gap where the terrain drops steeply into a canyon draining to the east. 

05a (maybe) layer cake
A level stretch before the next riser

Here the trail loses it’s northerly fixation and swings to the northwest. It becomes  a mild up-and-down ramble as the trail skirts around the headwaters of the intervening canyon and eventually swings back north. There is another short pattern of slogging up steep risers and crossing brief shelves. Eventually, at about 2.6 miles from the trailhead, come to the top of the ridge that is fronted by that yellow cliff band. As you arrive you will leave the Upper Sonoran behind and enter the Transition life zone. Juniper and pinyon  give way to Ponderosa Pine. 

07 Florida Mts from top of yellow ledge

At the ridge the trail turns sharply east. Glimpses north thru the pines reveal the antenna-strewn summit that is your destination. Views open up to the southeast, where the Florida Range dominates the horizon. The large bowl to the northwest contains the headwaters for Sawmill Canyon. Reaching point 7651 (shown on the USGS map) the trail finds a narrow ridge that will again allow it to resume its northerly course. This is very pleasant, Ponderosa-shaded terrain. There were deer, cow and horse tracks on the trail, but surprisingly little evidence of bootprints. Scattered along this section of trail is snowy white quartzite – sandstone that has seen some high temperature and pressure.

08 earthern cattle tank
Earthen water tank along the trial

At 3.6 miles from the trailhead come to an earthen water tank. It seemed nearly full on this date, but this is the end of monsoon season and in other times of year the water levels will vary. It is very muddy. You would want a serious pre-filter and filter system before using this water. (In fact, there is a water source just minutes away that often has clear water so you may want to hold off).  Past the tank come to the Jack’s Peak Road, a well maintained gravel road used to service all those antennae. Study this intersection carefully as you’ll want to recognize it on return. Then follow the road uphill. 

10 Mimbres basin and Cookes Peak

As you near the summit you will find a level stretch where a cabin once stood. All that is left is a foundation and a freestanding chimney. Are you looking for water? Go straight north, past the right-hand side of the chimney, and ascend a small rise. At the top you will find a large rectangular concrete catchment. From the north edge of catchment a pipe runs to a corrugated steel water tank and (below the tank) there is an open concrete trough. The trough currently holds about 6 inches of clear water.  To the north lies the highpoint of the range, Burro PeakFrom the trough return to the road and follow it to the summit. There is some serious looking communications gear here. Take a few fast snaps of the incredible terrain, including the eye-catching Cookes Peak, then get away from all that microwave activity.  Have lunch amidst the pines and return the way you came.

This is a wonderful hike on an autumn day. It might be chilly but it should be doable on most midwinter days. The lower slopes are poorly protected from the sun. It would be best to find another hike on scorching, midsummer days.

Most people will want to carry their own water for this hike. On this date a 700 ml bottle was plenty. On warmer days, of course, you would want much more. Comments on the Guthook app (a phone-based navigation app) report that the concrete trough near the summit was dry at earlier times this year. Try to keep your stays short when stopping near the earthen water tank and the summit trough. Those are both likely to be critical resources for wildlife in the Burros.

I saw a surprising number of cattle along the trail. Give the lack of grass on this hike these cattle may be pretty stressed. Go gently and give them as wide a berth as you can.

I saw a grand total of one lizard on this date. I suspect that the chilly nights of late have encouraged the others to den up.  The challenge poised by our venomous neighbors on the trail may be close to a minimum.

The 100 Hikes In Silver City site has a brief report on the trail (although not all the way to the summit).

CDT hikers give mention to this part of the CDT: Peter Shaw in 2011 here, Mudbug in 2016 here, and Kate On The Road Less Traveled in 2015 here (scroll down to Day 15). It is hard to do much more than hike, eat and sleep when through-hiking, so these mentions are understandably brief.
