rito, Sean 2004 Journal Convict Creek, Mono Co., CA August 6 Derham Dimiani and I hiked from Convict Lake up Convict Creek for about four miles to the point where the trail crosses the Creek at a washed-out bridge, of which only the concrete supports remain (see map in species account). We then turned up a side canyon to the north to look for a population of Hydromantes platycephalus that Derham had found some years ago. About 20 feet up the canyon on the east side of the stream, Derham turned one rock on the stream edge that was sitting on another rock and found a large adult salamander (SMR #16). He quickly found 2 juveniles in the same area. We then searched up and down both sides of the stream, including some small cops on the west side, and I found another juvenile some 50m up the stream on the east side among some rocks about 2 ft from the stream edge. We eat lunch and searched again near the canyon mouth. We found 1 more juvenile near the canyon mouth and 2 more adults and 2 juveniles about 50 ft upstream under some small rocks amid a thick growth of wildflowers (Compositae). All of the juveniles were golden in color and 1 1/2" - 2" long, and the adults were a fairly dark mottled gray color. The habitat was very different from sites in the high Sierra that I have seen, since it was a stream with a lot of water flowing very fast. There were many flowers around the stream along with some small ledges and whitetail pines (I think...), but the immediate edges of the stream were mostly bare rock. The weather was sunny, calm and fairly warm all day. I also stopped to look at the area around Lake Bridge in Mammoth Lakes, but did not see any suitable habitat.
