R. MOON 1987 Journal 97 27 May After Canyon, San Bernardino co., CA. Once again Bob, Bruce and I went on a half day expedition from the Granites to After Canyon on the Mojave River. Our goal was to set a turtle trap to catch some of the pond turtles in a small pond near the river. While Bob & Bruce set the trap I caught some bullfrogs in some different puddles near the river just east of the turtle pond. Then we walked upstream (west) and looked at the destruction of the oasis cased by cattle grazing and off road vehicles. We saw very many small toads and tree frogs in the short grass along a chain of small ponds in a side channel of the river. Our next stop was the Desert Studies Center at Soda Lake. We just wanted to see what the consortium was like. We looked around the classroom & lab facilities (which were in the works). We also walked along the edge of the lake bed and looked at the springs where we thought there might be some tree frogs. We didn't see any. Cont'd.
