My first inclination was Crater Hills Geyser, but that's just not it. The shape of the eruption and formation are all wrong, and as far as I know, Crater Hills Geyser hasn't changed its appearance much in the last 75 years. Also, it looks like there's too much open space-where are the trees and the other hills? It may be a mistake to assume that this picture was taken in Yellowstone--it still might be something obscure near Norris or in Hayden Valley, but I'm going to guess that it's something obscure in Nevada.

This photo was taken on October 17, 1931. It was _probably_ taken by Dr. E. T. Allen. Some of you will probably recognize the setting. For others, a possible hint lies in the fact that Allen communicated with people named Nolan and Anderson, and they wrote an article that appeared in the Americal Journal of Science in 1934.
