Larry has a Ph.D in geology from the University of Illinois in 1959, and taught mineralogy and other geology courses at California State University Northridge, beginning in 1960 and retiring in 1993 after 33 years of teaching. He is currently a member of the United Methodist Church in Thousand Oaks, California. He coordinates Lay Witness Missions for more than 100 weekend missions to churches, ranging in size from 60 to 6,000 members, and witnesses to how Christ has changed his life. He has been on the summer staff at Holden Village some 8 to 10 times, in the 1960s and 1970s. He returns on the summer staff this year for the first time since then. He enjoys leading hikes to the Holden copper mine, describing its geology and history. Together with his wife, Barbara, he has written some of the guides to the hikes around Holden, describing the local plant and animal life. In younger years, Barbara and Larry once hiked to Mirror Lake in one day, a 36-mile round trip!

He has a website Opposition to Creationism, and has been opposing a literal interpretation of the Bible for many years on the basis of scientific evidence. He plans to give slide sessions on the glacial geology of the Holden area, volcanoes, and why Moses kept his feet dry – the story of the disappearing island of Atlantis. He wrote an article for the January 1966 issue of National Geographic Magazine, “Rare Beauty in Common Rocks.”
