Knuts, Sean 2005 Journal July 8 60 Lake Basin, Kings Canyon National Park, Fresno C., CA After leaving the White Mountains on July 6, I hiked into the Sixty Lake Basin from the Onion Valley trailhead on July 7. Today I walked to a Hydromantes site in the basin above "Fjord Lake", on the way to Gardiner Basin. I placed data logger #883626 in a large east-facing crevice in the rocks where it should be protected from the weather (36.81306°N, 118.43306°W [WGS84, 9m acc.], 3367 m elev). There was some seepage in the crevice. I put the data logger out at 1:02PM. I found a juvenile salamander in the seep next to the logger. I looked under rocks in the area and got mouth swabs from 13 adult and subadult Hydromantes. I started sampling near the data logger, where I found most individuals in seeps under rocks. I continued for ~100m west and 30m up from the data logger. Most salamanders were found relatively low down, and I only found three higher up although the seep habitat was present much higher up the slope. The habitat looked excellent - bare granite with lots of seepage. There was no vegetation except for grass, moss and currant bushes, and the seeps were on a southern exposure. I saw two subadults that escaped before I could catch them and 10 juveniles that I didn't swab because they were too small. I called all but one adult a male because I could feel protruding premaxillary teeth, but I didn't notice mental glands on most individuals. For this reason, I stopped keeping track of the sex of each salamander.
