Original 1884 sketches from Phimister Proctor's scrapbook, courtesy of Sandy Church and Laura Ames, of the A. Phimister Proctor Museum. The sketch on the left was reproduced in Proctor's autobiography, "Alexander Phimister Proctor, Sculptor in Buckskin", University of Oklahoma Press, 1971, p. 78.

A drawing, based on one of the sketches above, was published in Proctor's booklet "An ascent of Half Dome in 1884", Grabhorn Press, San Francisco, 1945, and also in the Sierra Club Bulletin, Vol. 31, No. 7, 1946, pp. 1-9:
