Parked on Northshore Road and hiked a loooong way down through Pinto Valley to Boulder Wash, before heading up the gully to the saddle between Ram Skull Peak & Boulder Peak. From the saddle, I headed up the loose slope to Ram Skull Peak, then traversed over to Guardian Peak. I returned the same way, taking a slightly different way back to the saddle, then followed the ridges up to Boulder Peak. Hiked down the NE Ridge of Boulder Peak back to Boulder Wash, then returned the way we came. 19 miles in all. We saw a Bald Eagle, a Turkey Vulture, 5 bighorn sheep and 3 bighorn skulls along the way!
