Courtney enjoys backcountry exploring, hiking, backpacking, and photography. In 1990, he began visiting rock art sites during many of his days off and vacations and this inquiry slowly pulled him into the field of rock art research. This has led him to volunteer to record rock art sites in several states and eventually write or co-author scholarly papers on the rock art of Eastern California and Nevada for the Southern Nevada Rock Art Enthusiasts newsletter, the American Indian Rock Art publication of the American Rock Art Research Association, the Rock Art Papers of the San Diego Museum of Man, and in the Proceedings from the 2001 Millennium Conference. In addition, he has given presentations on a variety of rock art topics to various organizations that include: the Eastern California Museum, Audubon Society, University of California White Mountain Research Station, and the Mojave Rock Art Workshop.
In 2011, he was awarded the Mark Oliver Award from the American Rock Art Research Association for "Excellence in the Art & Science of Rock Art Photography.”
Courtney worked for Inyo County as a Planner and Transportation Planner before his retirement in 2018.
