Overview

This is a strenuous route that climbs some 2,600 ft from the valley floor to the summit of Hidden Peak, one of the higher peaks in the Arrow Range. The route crosses the valley, ascends a rocky bajada and canyon to the summit ridge, then follows the loose, rocky ridge north and eastward to the summit. The upper parts of the route have a little 3rd-class scrambling and lots of loose rock. As with all of the peaks in the Arrow Range, the views from the summit are spectacular.

Watch Out

Other than the standard warnings about hiking in the desert, ...this is a strenuous route with a little 3rd-class climbing, many pour-overs and loose rocks, and a lot of steep 2nd-class scrambling, but other than potential rock fall, this is a fairly safe route.

This is a wilderness area, so while hiking, please respect the land and the other people out there, and try to Leave No Trace of your passage. There are few cairns on this route; please don't leave any new ones. Also, this is a long hard hike, so be sure to bring the 10 Essentials.

This hike is located on the west side of the Arrow Range, about 45 minutes northeast of Las Vegas.

From Las Vegas, drive out to the west side of the Arrow Range. From the intersection of Interstate-15 and Highway 93 (Table 1, Site 674), drive north on Highway 93 for 23.1 miles. Stop by Mile Marker 75 (Site 880), well off the pavement. Park here; this is the trailhead.

The Highway Patrol may check your vehicle while you are away, so when you return, expect to find a notice on your antenna about abandoned vehicles.

The Hike

From the trailhead (Table 2, Waypoint 1), the route runs eastward for about 1.8 miles to the mouth of the major canyon (Wpt. 2) that runs diagonally across the face of the range (running up and southeast). Most of the canyons on the west side of the Arrow Range run straight up and down the scarf (east-west), rather than diagonally.

Initially, the walking is easy as the route winds among vegetation typical of the Upper Sonoran (Mojave Desert Scrub) life zone. Creosote Bush, White Bursage, and Mojave Yucca dominate the landscape, with many other species (including some cactus) mixed in. There is also a lot of cryptogamic (biological soil) crust in the bottom of the valley. The crust is a complex community of bacteria, algae, lichens, mosses, and other stuff that bind loose soil particles together, thereby stabilizing and protecting the soil surface from erosion. The little (1-inch high) peaks in the crust can take a century to develop, and to the extent that we can, we should avoid walking on the crust.

From the mouth of the canyon (Wpt. 2), the route runs southeast up the canyon all the way up to the saddle on the crest of the ridge. The route stays to the right at the first major fork, and to the left at the second major fork in the drainage (Wpt. 22). The lower canyon is a relatively low-angle, easy hike in the wash.

From the second fork (Wpt. 22), the route scrambles up the canyon to the left. This section of the canyon is steeper than below with lots of boulders and a few little pour-overs (minimal 3rd-class) to scramble up. Near the middle of the canyon, there is a place where some enormous pieces of quartzite fell from the cliffs and came to rest at the base of a pour-over. In January 2003, there was fresh rock power that appeared never to have been rained on, suggesting that the rocks might have fallen in the previous three weeks (it had snowed here on December 31, 2002) -- an interesting thought to contemplate while hiking in a steep, narrow canyon.

Continue up the canyon. Near the summit ridge, the canyon opens up above a slot in the cliffs (Wpt. 21). Continue walking generally southeast on the lower-angle slopes towards a saddle on the skyline.

From the saddle, turn north and hike up along the summit ridge. The hiking in this part of the route is easier to the east and south of the actual ridgeline. This bypasses some difficult spots and high points on the ridge, but it causes you to hike across rocky sideslopes. Along the way, you will pass another saddle (Wpt. 20), cut across side slopes (Wpt. 19), pass to the south of a knob (Wpt. 18), and climb onto a promontory just below some cliffs where there are interesting bands of thin black and white rock layers (like a stack of Oreo cookies) (Wpt. 17).

Higher up is still Upper Sonoran (Mojave Desert Scrub) life zone, but here the vegetation is dominated by Blackbrush and bunchgrasses.

From Oreo Promontory, which is only some 200 yards from the summit, the route crosses over onto the west side of the ridge where you must carefully pick your way across steep, rocky sideslopes and climb through short sections of 3rd-class rock to regain the summit ridge at a point quite close to the summit. Continue on to the summit (Wpt. 16).

The views from the summit are spectacular. To the east are Mormon Mountain and Moapa Peak, Moapa, the Virgin Mountains, and peaks up in Utah; to the south is the Lake Mead region and the southern parts of the Arrow Range; to the west are the Las Vegas and Sheep Ranges on the Desert National Wildlife Range, and to the north is the remainder of the Arrow Range and numerous mountain ranges beyond.

When you are ready to depart the summit, retrace your route down the ridges and down the canyon. Be sure to drop down along the west side of the summit ridge and hit the Oreo Promontory; it would be easy to get started on the ridge that runs more to the south, and this is not the easiest way to get back to the trailhead.
