Journal 1963 Borell Ojosagana, 5000 ft. el. Climbing resumed. Apr. 5 continued enough until 9 a.m. to restrict visibility to about 50 yards. The last of the fog held on until 11 a.m. Tracks showed that some of the salamanders reached the grassland around the lake and tracks of two led to the (possible?) sockets of rodent burrows. There was no evidence of frogs or turtles or large insect larvae in the playa. Notable by their absence were ococets, curlews, wrenter sandpiper, gulls, blue herons, and shorelers that were present on my last visit to the playa on April 2. Discovery of the salamanders in the playa may account for the previous presence of the blue herons. Among other food items in the salty playa water is a small bivalve. Its presence is indicated by undrows & tiny shells (sample saved).
