Overview
This is a tough 4th-class route that starts in the bottom of the valley
and runs up 2,750 vertical-feet to the summit of Peak 5146, one of the highest summits in the Arrow Canyon Range. One long
section of 3rd-class climbing, located high on the route, was described by
a fellow climber as being a very efficient route -- it was steep and run straight towards the summit. Just below the summit,
there is a 4th-class chute where some climbers might want a belay,
especially for the downclimb (with effort, the chute can be avoided). Views from many parts of the route are spectacular, as
is the exposure.
This route follows obscure gullies, and it is difficult to accurately describe each turn. Therefore, this description relies
heavily on the topo map and GPS coordinates, plus the climber's good route finding abilities.
This is a stout route that is not for the inexperienced or faint of heart.

Watch Out
Other than the standard warnings about hiking in the desert, ...this is a
hard route with many pour-overs, much loose rock, and lots of steep
2nd-, 3rd-, and 4th-class climbing. A rescue from anywhere between the top
of the alluvial fan and the summit ridge would be difficult.
This is a wilderness area, so while hiking, please
respect the land and the other people out there, and please 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.
Getting to the Trailhead
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 Canyon 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 probably will 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), walk eastward for about 1.8 miles to the mouth of the major canyon (Wpt. 4), the lower end of
which comes straight down the face of the mountain about 1,000 yards south of the summit. Another canyon (688000, 4062300; 2,800 ft) empties
onto the bajada about 300 yards south of this canyon, but that canyon runs diagonally up and to the southeast. |

Initially, the walking is easy as you wind among vegetation typical of the Mojave Desert, dominated by creosote bush and Bursage, but with lots
of other species (including yucca and cactus) mixed in. There is also a lot of cryptogamic (biological soil) crust in the bottom of the valley, and to
the extent that we can, we should avoid walking on the crust. The crust is a complex mixture of cyanobacteria, green algae, lichens, mosses,
microfungi, and other bacteria. The cyanobacteria and microfungi weave a network of filaments through the top few millimeters of soil and
exuded polysaccharides that bind loose soil particles together, thereby stabilizing and protecting the soil surface from erosion. The roughened
and stabilized surface then provides microsites for lichens and mosses to develop in the spaces between shrubs that otherwise would be bare.
The little peaks (1-inch high) in the crust can take centuries to develop.
From the mouth of the canyon (Wpt. 4), head east for about 20 minutes (600 yards) to the first major fork in the drainage (Wpt. 5). Passing the
lower canyon involves scrambling over and around numerous large boulders, many of which contain fossils (e.g., corals, sponges, crinoids, snails, and
nautaloids) that can also be seen higher up in the intact rock.
From the fork, scramble up the northern (left) canyon. About 400 yards out, progress appears to be blocked by a 30-ft pour-over (Wpt. 6).
However, it can be passed with a little 4th-class friction climbing by traversing in
from the southern edge of the cliff near the top of the pour-over (viewed from below, you climb across the top-right edge of the cliff). It looks
worse than it is, as the carbonate rocks are quite rough. This pour-over was a bit high for comfort and probably would be dicey to down climb
without a rope (the first step off the top is always the worst). |

Passing the pour-over, continue scrambling up the main canyon, climbing more little pour-overs, for about 50 yards to where a steep gully angles up
the northern side of the canyon (Wpt. 7). This is below the point where the main canyon angles off to the south (right). From here, cut up
and out of the bottom of the canyon, heading for a steep gully that runs up into the band of black rock on the north (left) side of the canyon.
Continuing up for about 70 yards, you get out of the main gully, climb more pour-overs, and get into the steep gully (Wpt. 8).
Continuing up for about 100 yards, you reach the bottom of another band of quartzite (Wpt. 9).
Continuing up for fewer than 5 minutes, climb a short, 3rd-class pour-over just above the
quartzite. Continue climbing this gully through the black band (this is the one described as being very efficient) for about 400 yards to reach
a promontory (Wpt. 10). This is the top of the difficult climbing on this part of the route. Relax on the promontory and enjoy the beautiful
view of the valley; it still is a ways to the summit. |

Climbing the 4th class gully.
|
From promontory, angle off to the southeast and down across sloping ledges heading for a saddle on the skyline about 220 yards to the east.
Walk down along the broad, rocky ledges; cut up through the cliffs near the saddle; and then cross a loose scree slope angling into the
saddle (Wpt. 11).
From the saddle, it is basically a 200-yard walk up and northeast across the summit slopes to the summit ridge (Wpt. 12A). The easy walk
gives you time to enjoy the view. Also notice that the vegetation on the upper slopes is more diverse than lower down. Here there is lots
of blackbrush, saltbush, a big species of buckwheat, bunch grasses, Ephedra, a few desert almond, a mound cactus with long red spines, and
lots of others species.
On the summit ridge, work north towards the base of the summit block (Wpt. 12B), walking around to the west side of a buttress. Here, easy
walking leads to a 30-ft high, 4th-class face that can be climbed easily or passed in a
hidden gully a few steps farther to the north.
From the base of the summit block, carefully climb the steep 4th-class gully on the southwest corner of the summit block. Most of the
climbing is on solid rock, but some is loose. Near the middle of the climb, there are some small, but interesting solution tubes (phreatic
tubes) in the rock where water flowed through the rock. Given more time, these might have widened to form a cave. I pulled loose a large
rock at the top of the most difficult part of the gully, which is still there, so be careful. |

Views from the summit are spectacular (view north).
|
From the top of the 4th-class gully (Wpt. 13), head north and up towards the summit, which
is only a few minutes away. There are two summits that look about equal in height; the USGS topo map marks the northern peak (Wpt. 14)
as the summit.
The views from the summit are spectacular. To the east lie 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 are the remainder of the Arrow Range
and numerous mountain ranges beyond.
When your spirit has been refreshed and you are ready to depart the summit, there are two basic choices for getting down: (1) downclimb the
ascent route or (2) hike south to the summit of Hidden Peak and descend the Hidden Peak route.
The second choice makes for a long, but safer way to get down. |
