Reamer expanded and altered his hotels at Yellowstone with a series of additions and alterations to the Old Faithful Inn, Canyon Hotel, Mammoth Hotel and the Lake Yellowstone Hotel from 1926 to 1936. Most notably, the Old Faithful Inn was expanded to include the present dining room and Bear Pit Lounge, and the Lake Yellowstone Hotel received a modest addition facing Yellowstone Lake that is known today as the Reamer Lounge. Reamer also added a dining room and lounge to the Mammoth Hotel. The Map Room Lounge includes seventeen-by-ten-foot map of the United States, made of inlaid wood by Reamer and his associate W. H.
