A large tract of land in the San Gabriel Mountains was leased from the United States Forest Service in 1888 to master trailblazer and cabin builder Louis Newcomb. Robert B. Waterman was a pioneer mountain man and a ranger in the San Gabriel Forest Reserve. Waterman, together with his wife Liz and their friend Perry Switzer, completed a three-week hike from La Cañada to the Antelope Valley and back in May 1889. With this epic feat, Liz became the first white (non Indian) woman known to have crossed the San Gabriels. Along the way, she placed a cairn on this summit, and christened it "Lady Waterman's Peak". However, attitudes toward women at the time led to this name being considered inappropriate. The peak was subsequently referred to by different names, all of which left out the "Lady". To his credit, Robert Waterman made numerous, futile efforts to have the full name restored.
