Hike Moapa Peak, 6,471': Knife's Edge Excitement

We met our match on Moapa Peak's fabled "knife edge" final ascent, and came within 160 feet of the summit.

Left photo:  the final ridge to Moapa's summit.  We climbed 3,200' to the high point in the foreground (seen just under the summit in photo), then turned around because this knife's edge seemed too exposed.

Trip Stats
Overview:  An enormous gray fin sticking out of the desert floor, Moapa Peak's knife-edge ridge tests the hiker's fear-of-heights-and-exposure factor.  Ascend a pretty braided stream wash and then prepare for a steep, rugged climb over sharp limestone the rest of the way, negotiating a few Class 3 rock faces, paying close attention to rock cairns that mark an elusive trail that aggressively elevates you to sneak under Moapa's southern summit block.  Gashes, chasms and sheer walls appear as you hike, with spectacular views of the empty desert far below.  Descriptions of the final exposed ridge to the top include "exhilirating", "thrilling", and "incredibly fun."

Prominence:  1,671'

Our GPS tracks from narrow point of wash (bottom) to near Moapa Peak's summit. Out of the wash, the trail climbs to saddle (lower left), then ascends over rock ledges, some of them Class 3, continues along southern base of summit block, then curves around at base of final ridge to summit.

Moapa Peak, included on the Sierra Club Desert Peaks Section list is a distinguished, stand-alone hulk of narrow limestone noticeable on the north side of  I-15 north of Las Vegas.  It's a classic desert peak, well-fortified by a series of almost vertical ramparts at its base.  It's one of the more memorable and exposed hikes I've done.   Trip reports reveal hikers who have summited, as well as those who reportedly turned around when they saw the final exposed "knife-edge" ridge to gain the last 160'.  After skirting around the south cliff face, the route wraps briefly to the north at a saddle, where the Class 3 climbing up the final ridge begins.  Although the narrow ridge proved too daunting for Fred and I, the hike was worthwhile because the steep drop-offs give the slight feeling that a few missteps may plunge you into the chasms and canyons below.  We found the "trail" mostly stable and easy to follow.  The views of the ribs of dark and sharp mountain ranges rising from flat and buff-colored desert washes are spectacular.
​
Occasional fossils appear in this Paleozoic limestone (see photos below).   I'm not sure what they are, so if someone knows, please contact me!  One of them looks like fish, another looks like petrified wood.

Harder than Mt. Katahdin's knife edge?
​Maine's Mt. Katahdin, it's highest, has a famous "knife's edge" traverse to the summit.  Fred and I summited Katahdin when we lived in New England and felt it wasn't too scary.  Reports say that it narrows to four feet of width in a few places.  I think Moapa Peak, which reportedly narrows to one foot, is more intimidating. 

Side note:  Mt. Katahdin is the northern terminus for the Appalachian Trail.  While we were on the summit, we saw a hiker who had just completed the entire trail arrive at the famous terminus sign.  I'll never forget the look on his face!  Some of his family was there to greet him.​

Hike Summary

• from Moapa Peak trailhead, the road leads past walls of dark chert layers in limestone and up a slight hill, where you see the wide braided-stream wash that leads the way to Moapa Peak.  Hike up the wash in a NE direction for ~ 1.5 miles to end of wash and beginning of climb to saddle.  We saw occasional cairns.  The wash narrows and boulders appear near head of wash.  Cairn on left side of wash marks trail that gets you out of the wash and heads toward saddle above.  The trail crosses the drainage shortly and continues steeply to the saddle on the right side of the drainage.  Saddle is 1.9 miles, 4,483'.
• Climb a series of ledges, two of them Class 3, looking for cairns that mark trail switchbacking up the steep slope.
• At 2.4 miles arrive at platform (less steep climb) to ascend northeast over another small saddle marked with a cairn to see the trail at base of south side of summit block.  At 2.8 miles, skirt around base.
• At 3.5 miles arrive at saddle between 2 high points on Moapa's eastern ridge.  Just as you go around to the north side, locate a cairn to guide you up Class 3 climb up a cleft to final ridge climb to summit.

I would avoid doing this hike in the summer months.  I know from experience, since we roasted on this hike last summer and turned around at the saddle because of the heat and intense sun.   

This is a unique hike that not many get to experience.   This beautiful mountain won't make it easy for you to gain its summit, or even get to its approach ridge.  The Nevada desert is stark and hard and the limestone unforgiving.  And, the only flat spot is found briefly on the saddle above the approach drainage.   Fred and I are lucky to be able to explore this exquisite part of the southwest.  Now when we see Moapa from I-15, we can see how high we got on that very vertical mountain.

Keep on Exploring!  Get It While You Can!

Park near trailhead sign.

Start by walking on road that leads to approach drainage.  Look at what we get to climb!

Road passes by impressive display of layered chert in limestone.

Occasional cairns mark way up braided stream drainage.

Drainage narrows.

A bit of boulder-hopping and maneuvering as you get closer to head of drainage.  Duck on the right boulder.

Trail continues left of large dry waterfall - entry to this trail that takes you out of the wash is marked by a cairn.

Once out of the wash, everything here is steep!

Cairns mark trail that continues up to saddle (top of photo).

Getting closer to saddle, then the trail goes up and works around the rock ledges ascending from saddle on the right.

Looking back down toward end of wash from the saddle.

At saddle, cairns mark trail that ascends the ledges and walls to the north, with some Class 3 climbing.

The trail continues over these ledges to the less-steep and more open terrain above at top-middle photo.

The trail ascends to the left of this huge wall.

Cairns mark trail as it transitions from the steep ledges to less-steep but narrow "platform".

Looking back at relatively flat platform above ledge section.

Getting closer to the summit!

Walking around south face of summit block.

Reach Moapa's east ridge for spectacular views to the north - Mormon Mountains.  Travel a short distance around Moapa's east ridge to the left to find cairn marking entry onto the final ridge to summit climb.

The northwest-facing side of Moapa Peak summit seen here.  At first, we missed the cairn to lead us up the walls on the left, so we kept walking along this north side for a short distance.  When we didn't see any footprints in the snow here (earlier we met a climber who was on his way down from the peak) and no more cairns, we went back to beginning of the ridge and found the cairn (bottom of photo) marking entry onto the knife's edge part of final ridge ascent.  It's here you take a left to find another cairn in the cleft on the left.

Making our way back down after turning around at scary knife's edge!  A bit disappointed we didn't summit, but still really happy we got that far on this unique hike with its breathtaking views and drop-offs, and steep, narrow approach.

Trail comes close to this deep chasm.

On the way back heading toward saddle that leads to platform above the ledges section.

Snow-covered Virgin  Peak in the distance to the east.

On the way down:  view to the west of Nevada's parallel mountain ranges caused by extension in the Great Basin tectonic province.  Great Basin rifting (extension) is the second major tectonic episode that shapes this area; it began ~ 30 mya and continues today.  Normal faults result from extension - a pulling-apart of Earth's crust.

Tilted sedimentary beds.  Nevada is interesting because it has undergone major tectonic forces of mountain building, shearing, faulting and rifting.
