Harris, Dean 2007 Journal Olancha Creek, Inyo National Forest, Inyo Co., CA June 1 I drove along the LAOWP canal behind Olancha and parked where it meets the creek. I started at 11:45 and hiked up on the N side of the creek (much easier than other side) to near the mouth of the canyon. I climbed up the steep slope north of the canyon mouth to a small saddle and then tracked down on the other side to the creek. The creek is impassable starting from the mouth, so this is the only way in. I started climbing up the creek and searching. I got to a spot where there was a damp, mossy/dirty area next to the creek that may have seeps also or it in wet periods. I found 1 juvenile and 3 adult H. platycephalus here under rocks (36.26535°N, 118.07087°W [WGS84, 2Gm acc.], 1719m elev.) at 15:09 and collected 2 adults (SMR255+256). Continuing up the creek, there are some nice cascades and mossy seep areas that look like perfect habitat. I found another adult H. platycephalus under a rock along the stream (36.26461°N, 118.07266°W [WGS84, 11m acc.], 1760m elev.) at 15:40. Continuing up, I got to an area with willow covering an area along the stream, with some rocks sitting in leaf litter. I found a subadult (SMR257) and a juvenile Batrachoseps holbrooki under 2 of these rocks, as well as 2 juv. H. platycephalus under the same rock about 1m away from the Batrachoseps rock (36.26482°N/118.07347°W [WGS84, 7m acc.], 1779m elev.). A short distance upstream, I found a big adult Batrachoseps and a juvenile Hydromantes under the same rock! (SMR258). A bit up upstream, I found 2 juvenile Hydromantes under a rock on a big granite exposure along the stream at 16:40, at which point I stopped searching and headed back.
