Three other carcass walked toward the pool area from cliff top N. of falls brink. 4:39, more visible on Roost Tree or Whitewash Ridge, but one in pothole near the ledge & at least 3 atop cliff over Big Cave near falls (big probably). 4:42, a lone adult descended, fast down, near Rock Ridge & alighted on top branch of a dead P. in the shade about 100yds. NW of Rock Ridge, saw in the canyon. Saw this adult shake head violently 3+ times. The tree was whitened as if used before for roosting- others were in sunshine still 100+yds. up the slope. 4:48, at least 6 visible at Big Cave area, one atop cliff, none on Roost Tree; frequent shift-ing still. I left Pyramid 20 & drove to Old Cabin. Saw 7 at Big Cave at 5:05 but could spot none on Arundell Ridge. Saw 1 late-comer descending northward over Arundell Ridge.
