(23 Gill, Douglas E. 1964 As it turned out we were on the ridge Larry had tried to go around the other night and we were just 50 feet about where I had been standing. We decided to leave our packs here and work this one ridge to the floor of the crater. Larry, Warren, and Dave Bratley had worked this ridge two months earlier and had determined that this was the center of the Dark-rumped population. I went down the right side of No. 2 (see map opposite) to get a skeleton I had left there the other night. I should mention that the map opposite is a view from the center of the crater looking at the side we worked. After I got back to camp, I worked down the base of the left side and Larry the right of No. 2. He then worked No. 3 as I worked through No. 7. A well used goat trail circled the outcropping of No. 7 and there were no burrows at all. As I worked the rocks on the grassy slope of No. 4 Larry discovered a chick in a burrow at No. 5. Success! I joined him and we revelled in our discovery. Larry banded it and now holds the first record of a banded Hawaiian Dark Rumped Petrel chick. (A dubious honor). I worked down the left side of No. 6 while Larry continued to work the upper ledges. He got high strung and had to back track to reset me down at the base. We then went down to the floor of the crater and looked for a burrow Larry had found two months ago but we couldn't find it. We decided to go over to Holua Cabin since it was so near, so we got on a trail which took us over the small ridge. We drank from the horse trough and decided not to go into the cabin since people were there. I wonder what the people thought when they saw these two tramps come out of nowhere, drink from the horse trough, and then quickly disappear. We went over the ridge without following the trail and started our ascent. It was real steep and I chose a slow steady pace which put me
