Gibson later coached the line at Carleton College and signed a contract to play with the Green Bay Packers but did not play.[5] Instead, he chose to earn his Ph.D. in geology from the University of Minnesota and became a geology professor at Carleton College, where he also coached the football team from 1934 to 1938. In 1936, Carleton went 6–1 with the only loss coming to Iowa. His coaching record at Carleton was 21–13–2.[1]
In 1938, Gibson worked as a geologist for the Socony-Vacuum Oil Company in Egypt. In 1941, he took a job as a geologist for the Magnolia Petroleum Company[6] and moved to Midland, Texas.[7] He later worked as a geologist for the Richfield Oil Company and for the Seaboard Oil Corporation. In 1952, he started his own consulting business and worked as a geologic consultant in the Philippines, New Zealand, Turkey, Egypt, South Africa, and Lesotho, as well as in the United States.[8] He was inducted into the Petroleum Museum Hall of Fame in 2001.[9]
Gibson died at his home in Midland, Texas on August 19, 2004, at the age of 98.[7]
