Alfred A. Hart was employed as a photographer by the Central Pacific Railroad. His job was to document construction and promote the route. While some photographers were satisfied with just pulling off the road for a shot, Hart would seek out unique views, even if that meant transporting his camera and equipment for miles and climbing, in this case, nearly 1,700 feet. This view is from the southeast ridge of Castle Peak at an altitude of 8734 ft. Photo location 39° 21.777'N 120° 20.645'W Note: Original description on the CPRR stereo card said "From the North-west" but probably should have read "Looking Northwest."
