Attached is a copy of page 480 in Allen and Day's "Hot Springs of the Yellowstone National Park". The geyser in the photo is "New Crater", aka Steamboat, and was taken by the Haynes Picture Shop. While the angle is slightly different, it is the same feature that is on the URL provided by Janet. Prior to 1905, the major eruptions of Steamboat were not widely known and most believed the activity to be like that shown in the photo.
