Douglas E. Gill 1964 returned to the chick and took 3 photographs of it. He then decided to work up towards camp checking his burrows as he went. I decided to work my rocks (No. 4) then up the left side of No. 2 and agreed to meet him in about an hour. Just as I started to go across the grassy slope into the rocks I slipped on a loose boulder and bounced twice. I banged my left shin but thought I only bruised it.
