He continues to work as a whitewater rafting guide in Grand Canyon. Larry has authored many publications, including recent books on river running in Grand Canyon, the ecology of springs ecosystems in North America, and global biogeography.
He is presently curator of ecology and director of the Springs Stewardship Institute at the Museum of Northern Arizona in Flagstaff, bringing to bear 45 years of scientific research on springs and aquatic ecosystems, land and water resources management, and advisement to Tribes and all levels of governance about those topics.
