Ravito, Dean 2005 journal June 9 Summit of Bald Mountain, Sierra National Forest, Fresno Co., CA I drove from Cottonwood Creek around the south end of the Sierra to Bald Mtn. Lowell Adams found a juvenile H. platycephalus here, and I came last year but it was totally dry. I hiked to the top and started looking at a large area of seepage below a big snowpack on the north side of the mountain. The granite here is in big slabs, creating long crevices in the seep, and looks excellent for the salamanders. The seep was quite wet but didn't really have water flowing over it. There was no vegetation besides moss. I found an adult female H. platycephalus (SMR30) in a crevice in the seep 10m N of the summit benchmark (37.10389°N, 119.20608°W (WGS84, 7m acc.), 2381m elev). I looked all over the seep areas that I could safely reach and flipped rocks for an hour but didn't find any more salamanders. I searched from 9:30 - 10:30PM. The rest of the mountain had some damp areas, but nothing I saw elsewhere looked great for the salamanders. There is plenty of granite, so the subsurface habitat is probably quite extensive. The one salamander I found was quite stout with a thick tail. It had smaller black spots that were more numerous and dispersed than usual, and it looked a lot different from most H. platycephalus individuals I have seen in the past.
