Robert Underwood Johnson also encouraged Muir to establish the Sierra Club, to, as Muir put it, “do something for wildness and make the mountains glad.”

The Sierra Club Outing or High Trip was one the benefits of membership in the organization. Muir (3rd from right) would frequently join these trips like this one Porcupine Flat in 1907. (John Muir Papers, Muir with others at Porcupine Flat)
