The 1916 Sanborn map shows Butte’s Main Street slightly before the beginning of Prohibition. The Rockwood Hotel is circled in red

The hotel is blue because it is made of stone, unlike the other surrounding buildings—made of brick, they are represented in the color red. This demonstrates how unique the high-quality construction of Rockwood was in the area. | Source:
