The peak was first climbed on June 19, 1938 by a party led by famed explorer Bradford Washburn; the climb took almost two months owing to weather delays. Today's standard route is the North Ridge. Despite being much lower in elevation than Denali, Marcus Baker is a similarly serious ascent, due to the remoteness of the peak and the resulting length of the approach and climb. A number of noted climbers have perished or sustained permanent injury in attempting to summit the peak as climbing conditions can change rapidly as storms arise. In early 1988, a State of Alaska Fish and Game biologist, 28-year-old Sylvia Jean Lane, succumbed to hypothermia as a two-day storm separated her from the two others in the climbing party attempting to dash to the top in a winter ascent.
