Overview – Mummy Mt Grand Crossing | Foxtail Canyon > Mummy Summit > Deer Creek Road | Spring Mountains, Nevada

Mummy Mt Grand Crossing Route Description

This adventure begins at the Foxtail Picnic Area in Lee Canyon. From there ascend through the picnic area, an abandoned Girl Scouts camp and on up to the Lee/Kyle Canyon summit rim. Take a left to connect in about a mile with the main Mummy Mountain summit route, taken by many who start at the Trail Canyon Trailhead in Kyle Canyon. Only, in this case you connect with the summit route near the final summit approach to Mummy Mountain.

After summiting Mummy Mountain, head down the avalanche slope chute on the opposite side of the mountain, the Eastern cliffs area. Navigate over to Mummy Springs and then descend via the Cougar Ridge Trail to Deer Creek Road. Take a mountain bike stashed there earlier down Deer Creek Road to Lee Canyon Road and finally to your starting point at the Foxtail Picnic Area.

Mummy Mt Grand Crossing Preparation

I recommend a base conditioning level of at least 5-miles running 4 times weekly along with one day topping 10-15 miles. Be altitude conditioned at the 11,000ft level, have wilderness navigation experience and ability to navigate very steep, long avalanche slopes.

In addition, have summited the Lee/Kyle Canyon summit rim at least once successfully from the Foxtail Picnic Area and summited Mummy Mountain from that rim. Also, have descended the Eastern slopes of Mummy Mountain previously and navigated through the wilderness to the Mummy Springs area and on down the Cougar Ridge Trail to Deer Creek Road. The links in this paragraph will take you to those adventure description pages, videos and pictures. However, once this adventure is completed you will see all the various parts together in one video on this page.

Route Starting Point – Mummy Mt Grand Crossing | Foxtail Canyon > Mummy Summit > Deer Creek Road | Spring Mountains, Nevada

Take Hwy 95 North from Las Vegas. Turn left onto Lee Canyon Road (Hwy 156). Continue on Lee Canyon Road about 16-18 miles, passing that road’s intersection with Deer Creek Road. Continue on Lee Canyon Road to take turn-around and park in a long parking area on the East (left) side of Lee Canyon Road just below the entrance to the Foxtail Canyon picnic area. Note: The tables in the picnic area are by reservation only, so, unless you’ve made a reservation do not plan to set up a picnic at one of the tables.

Route Observations – Mummy Mt Grand Crossing | Foxtail Canyon > Mummy Summit > Deer Creek Road | Spring Mountains, Nevada

I’ve previously worked out every part of this adventure. Today I put all the parts together:

1. Ascent from Foxtail Picnic Area on Lee Canyon Rd to the high ridge between Lee & Kyle Canyons (wilderness, no trails)
2. Traversing the high ridge to Mummy Mountain (wilderness, no trails)
3. Final ascent to Mummy Mountain summit (trail, a bit sketchy in places but decent)
4. Descent down the Eastern cliff of Mummy Mountain (wilderness, no trails)
5. Traversing the wilderness below Mummy Mountain to Mummy Springs trail. (wilderness, no trails)
6. Mummy Springs Trail to Cougar Ridge Trail to Deer Creek Picnic Area (decent trails)
7. Mountain biking from Deer Creek Picnic Area to Foxtail Picnic Area (new adventure)

Major learnings that will come out in the video:

1. Smoothed out the approach route from Foxtail Picnic Area to the high ridge between Lee and Kyle Canyon. The key is staying on the ridge above the Foxtail Canyon wash rather than descending into the wash near its summit. The ridge has a better surface, smoother going, conserves energy which will be needed later.
2. Descending the Eastern cliffs of Mummy Mountain is slow, careful going and takes a lot of time. I’ve done this before, but was again impressed with the difficulty of this stretch. If you lose your hold you could slide a long way to a hard landing!
3. Beautiful surroundings: Mummy Mountain is my favorite summit in the Mt. Charleston Wilderness and always like experiencing it for the first time.
4. Temperature differential: The temperature on this day was between 110 and 118 in the Las Vegas Valley depending where you were in the valley. My temperature on Mummy Mountain and throughout this adventure was a comfortable 75-75 degrees!
5. Time allotment: The adventure took 12 hours including 2-3 hours for filming and for rest. 
6. Energy expenditure: I was spent during the final 1/8th mile approach to Mummy summit. Fortunately, the rest was downhill all the way and I had more energy at the end of the adventure than at the half way point on the summit.
7. Definitely work out all the individual parts of this adventure before attempting the entire circuit in one day. It’s especially important to ascend the Eastern cliffs of Mummy Mt a couple times and descend at least once before placing that stretch within a larger adventure.
8. The mountain bike on the final 5-6 miles on Deer Creek and Lee Canyon Roads was essential as opposed to walking or running that stretch! It was quite the refreshing experience to sit on a bike and coast downhill at the end of this long adventure. Alternately, if you have two cars, use them!

Overall, this adventure is tremendous fun and pulls together 2 large canyons in the Mt. Charleston Wilderness and gives a more familiar relationship with the massive spectacular Mummy Mountain!
