After two years at the University of California Berkeley, John W. Ryerson (1917-1996) came to Alaska with a friend in the summer of 1938. They were employed in construction of a wooden gold dredge on a tributary of the Goodnews River. That fall, they took a short course in mining at the University of Alaska in Fairbanks and remained enrolled through the spring semester. Ryerson spent July and August of 1939 working at a placer mine on Harrison Creek near the Yukon River, and from September to November he worked for the Fairbanks Exploration Company at Ester. He left Alaska soon thereafter.
