James R. Evans was a geologist, mining engineer, and prospector who traveled through California’s Imperial Valley in the 1920s.
Little biographical information is revealed about Evans within the journal. During a significant part of the diary, he travels
and lives with Anne L. Evans, though he does not explicitly state that she is his wife. At one point in the diary, he includes
excerpts from her diary revealing that his nickname is “Jim” or “Jimmy.”
