2005 Roots, Sean Journal along the Merced River on Highway 140, Mariposa Co, CA January 21 Fed Paperfuss and I went to Sweetwater Creek to find H. burnus. We searched the seeps along the road and the rock along the creek thoroughly for 2 1/2 hours but found no Hydromantes. The habitat looked ideal, especially along the creek. I collected an Erythrina and two Batrachoseps (out of a total of 7 I saw). We checked a number of other seeps along 140 almost up to the turnoff for a geological exhibit but found no more salamanders. We drove to the type locality and I found one adult H. burnus at about 10:15PM, I tried to take a buccal swab, which was a dismal failure, so I settled for a skin swab from its ventral side. Finally, we looked around at the bridge where 140 crosses Bear Creek, where Stelling collected two H. burnus, but the habitat seemed off and we didn't see anything in about 10 minutes of searching.
