J.D. Anderson 1957 Ambystoma macrodactylum Jan 25 Valencia Lagoon, Rio del Mar, Santa Cruz Co., Calif. Sketch on bottom of preceding page - arrows indicate location of ad. salamander + direction of movement. Large clump at E end of pond area may be correlated with the many rivolets which flow down from woods at this point. One person found crawling down in such a rivulet. When released she turned back towards woods but when placed back in rivulet she followed it towards the pond area. Could be that salamanders use routes below to find feeding areas.
