Trailhead by quartzite outcrop (view NW) Overview This interesting, 3-3/4 mile off-trail route runs up long, gentle sandy washes and steep, rugged ridges to the summit of McCullough Mountain in the South McCullough Wilderness Area. From the trailhead, this route runs north over a low ridge to a sandy wash that is followed high into the mountains. Ridgelines then lead to a saddle on the crest of the range. From the saddle, the route drops into a wash on the west side of the crest that is followed upstream as it curves around beneath the summit. Sidehills lead to the summit.

North side of ridge above wash (view NW) From a distance, the McCullough Mountains look old, soft, and rounded, but these ancient metamorphic mountains harbor very complex terrain (they have been faulting and weathering for 1.7 billion years!), so this is not simply hiking up washes and ridges to a high point; it is, however, a good adventure in orienteering. The route starts at the upper edge of the Mojave Desert Scrub (Upper Sonoran Life Zone) and climbs into a Pinyon-Juniper Woodland (Upper Sonoran Life Zone) with some stately old California Junipers near the summit. On the ridges, the trees, mats of pricklypear cactus, and banana yucca make for considerable winding around and slow, careful going. Despite the relatively low summit (7,026 ft), the peak towers over the surrounding landscape and the views from the upper ridges and summit are spectacular.



Open wash (view NW) Watch Out Other than the standard warnings about hiking in the desert, ... this is a fairly safe hike. The ridges and sidehills are steep with loose rocks, but there are no cliffs or other unusual obstacles. The rocky outcrops look like good rattlesnake country, but unfortunately I saw none. The major concern on this hike is the loose footing among dense yucca and pricklypear cactus. While hiking, please respect the land and the other people out there, and try to Leave No Trace of your passage. This hike goes into the South McCullough Wilderness Area, so pay particular attention to respecting the land. This hike runs off-trail where nobody will find you, so be sure to bring the 10 Essentials. Cell phones work from ridges high on the east side of the crest, but I could not call out from the summit or ridges where I could see down the west side of the mountains to civilization.



Ridge traverse (view W) Drive west on Pine Spring Road for 1.5 miles to a fork (Site 1302). Stay right on Pine Spring North Fork Road and follow it to the Washes Route Trailhead (Site 1303) or to Pine Spring and the Ridges Route Trailhead (Site 1304) at the end of the road. Pine Spring is an acceptable trailhead, but it is easier to drive back down the road for 0.4 miles to a large outcrop of white quartzite boulders on the north side of the wash. Park by the quartzite outcrop; this is the trailhead (Site 1303).



Wash on W side of crest (view N from above saddle) Walking in the firm sand and gravel is easy. The route bends to the north at the first major fork (Wpt. 03), and again stays to the right at what seems like a minor fork (Wpt. 04). After a short narrow section, the wash widens again, and somewhere in there, the juniper species changes from Utah Juniper (the common species in southern Nevada) to California Juniper (the common species in southern California). High in the wash, it becomes advantageous to climb onto the ridge to the north. Leaving the sandy wash at a side gully immediately above a juniper (Wpt. 05) lying across the wash (forcing hikers to climb across a rocky outcrop on the side of the wash to get around it) is a reasonable solution. This route up this steep section passes beneath a rocky outcrop (Wpt. 06) and climbs onto the ridge above (Wpt. 07).



Majestic old California Juniper in wash (view north) From the ridgeline (Wpt. 07), the route runs west and up the ridge, weaving among Banana Yucca, pricklypear cactus, other shrubs, and Singleleaf Pinyon Pine and California Juniper trees. When the grade steepens below a high knob (Wpt. 08), the route cuts northwest across the side of the knob to gain the crest of the McCullough Range (Wpt. 09). The crest provides a great view down the canyon to the west with Interstate-15 and Clark Mountain in the background. On the crest, the route runs north and descends to a saddle (Wpt. 10). At the saddle, the route drops off the west side of the ridge and descends a short distance to the sandy wash below (Wpt. 11). In the wash, the route turns north and runs up the canyon. The fairly narrow canyon jogs to the west and then northwest again, and eventually opens into a fairly wide canyon with relatively low ridges on all sides. In this open area, there are some stately old multi-trunked California Juniper trees with thick trunks, shaggy bark, and trunks to about 20 feet high.
