Originally from Nebraska, Berle Mercer first came to Alaska while serving in the U.S. Army and being stationed in Anchorage. After marrying his wife, Claire, in 1950 in Nebraska, they returned to Alaska. They first lived in Nenana and then in 1957 bought a homestead along Lignite Road near Healy, Alaska where they raised livestock. Since the 1950s, Berle had an on-going relationship with Denali National Park. For several years, he hauled freight via horseback to the McGonagall Pass cache site for climbers attempting the Muldrow Glacier route on Denali. He also helped with several rescue operations. Berle and Claire were active in the Healy community and in the 1960s and '70s operated a gas station on the Parks Highway for several years while continuing to raise livestock. Berle passed away in 2008 a week after his wife's death. For more about Berle Mercer, see his obituary in the Fairbanks Daily News Miner newspaper.
