South McCullough Wilderness

The South McCullough Wilderness encompasses the southern portion of the McCullough Range. From a distance, the mountains appear soft, with mellow rounded edges. Upon closer inspection, you will see that the peaks and ridges are rocky and rough, reaching heights over 7,000 feet. The mountains in the South McCullough Wilderness are comprised of dramatic uplifted fault block of gneiss and granite, with steep slopes, narrow deep canyons to the east and west, and deep sandy washes. The mountains are formed of banded and foliated metamorphic rocks, dating back 1.7 million years ago, that have been uplifted and eroded. Bands of quartzite are layered in metamorphic rock, giving the rugged outcrops a striped appearance.
