Clinton D.A. Dahlstrom *52

Clinton Dahlstrom, a retired executive with Chevron Corp., died Jan. 16, 2015. He was 89.

In 1947 and 1949, Dahlstrom earned a bachelor’s degree and a master’s degree from the University of Saskatchewan (Canada). In 1952, he was awarded a Ph.D. in geology from Princeton.

He then worked in mining in British Columbia. Persuaded by his friend, Gerald G. L. Henderson *53, Dahlstrom joined Chevron in Calgary and worked there from 1955 to 1970. He was then transferred to the head office in San Francisco to become vice president of the mining division. He retired from Chevron in 1990, and gave more time to his sport of internationally competitive long-range rifle shooting.

Dahlstrom was known for his clear descriptions of the structural geology of the eastern section of the Canadian Rocky Mountains. His 1970 paper on the Alberta Thrust Belt helped popularize many structural styles that are now viewed as common features of many thrust belts. For his work, he received honors and awards from the Geological Society of America and the Canadian Geological Society.

Dahlstrom was predeceased by Phyllis, his first wife. He is survived by his second wife, Patricia, to whom he was married for 23 years; two children; and two grandchildren.
