luto, Dean 2005 Journal Bridalveil Falls, Yosemite National Park, Mariposa Co, CA (east) July 23 a tree growing on the north side. I walked up to the west side of the falls at 9PM, but couldn't get too close since the spray is still intense. I found five adult H. platycephalus under rocks and in mossy cracks filled with liverworts. The salamanders looked darker in color and more mottled than usual. I found them all along the cliff or very near to it, rather than on the rocky slope. I searched until 10:30PM and up to the edge of the spray zone but couldn't find any more. I swabbed all 5 salamanders but didn't get photos because of the intense, soaking spray. I released all salamanders where I found them. I need to return to try to get 10 swab samples, perhaps when the flow over the falls has diminished.
