There are several, however, the two most famous are likely Margaret Crawford and Doc Susie. In 1874, Margaret Emerine Bourn Crawford made her way across Rollins Pass to ultimately settle in Steamboat Springs. She and her family encountered a 2-hour blizzard in June and she wrote of the condition of the road, "the bumping was so hard I thought I was nearly dead." Several decades later, Susan Anderson, MD—Doc Susie—made her way into Fraser by way of the Moffat Road over Rollins Pass and was one of the first women to practice medicine in Colorado. She served as a physician in Grand County and was instrumental during the 1918 pandemic; she was posthumously inducted into the Colorado Women's Hall of Fame in 1997.
