He co-authored the 1965 book, "''Routes and Rocks: Hiker's Guide to the North Cascades from Glacier Peak to Lake Chelan''". He is credited with several first ascents in the North Cascades, such as South Spectacle Butte and Sitkum Spire. Dr. Crowder died on April 8, 1970, the innocent victim of a senseless automobile accident in his home community of Portola Valley, California. He is also the namesake of Mount Crowder in Antarctica, where he also had a work assignment.
