When starting to pack up, we found a cicada on our tent next to its molted shell. Our guide
              Lynne found a snake in her boat; Jeff, one of the guests, identified it as bull snake, and let
              everyone hold it before relasing it in the bushes. We got into the wooden dory for the day with
              Pablo, who we realized had been a guide as our 2001 trip!
              
              
              We rafted through five rapids, then scrambled over a short trail to Elves Chasm, a magical
              pool with a waterfall. We all climbed up and jumped off; Evan did it at least five times.
              
              
              After lunch, we saw lightning over the rim as big dark clouds rolled in. We pulled over as it
              started to rain, put on rain gear, and the rain stopped. We went into Blacktail Canyon to wait
              for the storm to pass. Gary described the "Great Unconformity" in the rocks: 540 million
              year old Tapeats Sandstone stacked directly on top of 1.8 billion year old Vishnu Schist.
              Over a billion years of rock formed, then eroded away, leaving a gap in the rocks of over a
              billion years. Guides Lynne and Pablo played music and sang songs while we lounged on a ledge
              across from them.
              
              
              Back on the river, we rafted through another four rapids, then made camp across from Randy's Rock
              at river mile 127. After dark, Jeff found scorpions in the bushes by making them glow with a
              black light flashlight.
