Bridalveil Falls, Yosemite National Park Mariposa Co., CA August 2 I drove from Berkeley to a tributary of Bear Creek along Hwy 140, 1.9 road miles S of Bridalveils where Fed had collected 2 H. brunnii last winter. I parked in the pullout on the W side of the road where Fed said he found them. There is a stream (with a little water in it now) flowing down a rocky bed into a stone culvert next to the pullout. I climbed up the streambed a few feet and deployed data logger # 873956 next to a large rock [illegible] a few feet NW of the stream (37.58627N,119.96510W [WGS84, 10m acc], 577m elev.) at 7:40 PM. It is on the NE side of a large rock, partially sheltered by it, amidst poison oak and other vegetation. I then drove to Bridalveil Falls and walked up to the base of the falls on the W side. I started searching at 8:50 PM and immediately found 4 H. platycephalus in the same spot as last time. I searched until 9:50PM, from very near the base of the falls over to where the rocks were dry but found no more. The flow over the falls is less than last time I was here. I got mouth swabs from all 4 animals but no photos- didn't bring my camera because of the spray The day was hot and the night was cool in the 60s, and clear.
