Little Ajo Mountains Archives – GlassMountains Trip Reports

On Thursday, March 27, Linda and I found a somewhat secluded campsite off Darby Spring Road south of the town of Ajo, Arizona. Here we spend the next three nights with our dogs. I hiked my second peak, Peak 2976, on Saturday. Meanwhile, Linda explored the Sonoran Desert near our camp on her mountain bike with our dogs.

Linda and I recently boondocked near an abandoned mine off the Darby Well Road southwest of Ajo. Over the next two days I climbed Sauceda Benchmark and Black Mountain (Pima) while Linda explored the area on bicycle and foot. It was a sheltered and pleasant campsite.

This Black Mountain has 1328 feet of prominence and lies in the Little Ajo Mountains of Pima County south of Ajo. The northern slopes appeared quite steep from our campsite but some friends had found a good route up its southwest ridge that I intended to try.
