Looking back into The Valley at first light. We'd spent the night lost along the base of Half Dome. We couldn't find the trail connecting the base back to the Death Slabs. Repeatedly we went down and back up 3 or 4 different manzanita choked paths. Each of the cliffed out at a dark slab. Around 3am Corey found the secret passage and we started down, hitting the fixed lines as light began to fill The Valley.
