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
