Moore, the seventh governor of the territory. Moore was Van Trump's brother-in-law. Van Trump first saw Mount Rainier in August 1867, and later recalled: He and Hazard Stevens made the first documented successful climb of Mount Rainier on August 17, 1870. They climbed the mountain via the Gibraltar Ledges route. Van Trump climbed the mountain at least five other times. Van Trump guided John Muir to the summit of Mount Rainier in 1888. Muir describes this climb in a chapter of his book Steep Trails. Muir and Van Trump kept in touch after the climb.
