Paso Robles, San Luis Obispo 2006 Journal Bridalveil Falls and Cathedral Lakes, Yosemite National Park, Mariposa and Tuolumne Cos., CA Aug. 3 I started the day by trying to drive to the South Fork of the Merced, but Hwy 140 was closed before the confluence due to the rockslide. I drove to Cascade Creek and hiked up to the falls closest to the road. The area around the falls looked good for salamanders, but was inaccessible due to a large pool at the base of the falls and because of the sheer granite walls. I next went to Bridalveil Falls. After ~30 min of searching, I found it, offloaded the data at 1315 and pulled it out (37.71708°N, 119.64800°W [WGS84], 14m acc., 1275m elev.). I walked up to the falls, which were blowing from side to side erratically, making it hard to search. I searched most of the spray zone from 1325-1350, but water was pouring down periodically into the spots where I have seen salamanders before under rocks; I suspect they could not be under the rocks or on the ledges in these conditions. The cracks across the cliff might still offer them protection. I found a single dead, battered and decomposing H. platycephalus at on the same ledge where I have found salamanders before and collected it (SMR145). Finally, I hiked into Cathedral Lakes near Tuolumne Meadows and camped there. I explored the seeps above the lake where I found a single H. platycephalus in August 2004 (SMR18). I started searching at 2045. There was extensive water flow over the granite in the seep areas and conditions looked very good. I found the first salamander at 2158 and proceeded to find 3 more. All were on the west side of the seep zone, in
