Multiple references throughout the transcript to Valerius Geist's book about mule deer. Discussed in the context of theories about mule deer evolution, the 'shirker male' hypothesis, and various behavioral theories. One speaker says 'I've read Val Geist's book' and another confirms 'Oh yeah' and 'in his book.' The book appears to cover mule deer origins, evolution, and behavior patterns.

Context:

Explicitly mentioned as 'that journal The Trapper by Osborne Russell.' Described as documenting the travels of a trapper moving through the Greater Yellowstone Region in the 1830s. The speaker notes Russell 'wrote down in enough detail his journeys every day' and that 'historians could go back and trace his path.' Used to discuss historical wildlife populations, particularly bison and bighorn sheep abundance.
