The Sanborn Fire Insurance Maps provide a wealth of information for historical research, often telling us the size and layout of buildings, the nature of their construction, what kind of business was there, and much more.

For example, poring over the 1884 Sanborn for Butte I made the discovery (surprising to me, anyway) that there was a mine at the intersection of West Mercury and Jackson Streets. Silver Bow Mining Company’s Stephens Mine had a 2-story hoist engine room with a steam pump and a fifty-foot 1½-inch hose. Two boilers generated 80 horsepower, and an attached carpenter shop was apparently reached by a ladder from Jackson Street. Jackson Street was effectively the west edge of town and is labeled “Arbitrary” on the map. A nearby blacksmith’s operation stood near the center of the present-day intersection, with the mine complex and shaft in Mercury Street, along the south side, just west of Jackson. The mine buildings totaled about 70’x70’ and there was also an 80-foot-long wood pile located at what is now the northwest corner of the Jackson-Mercury intersection.

The Silver Bow Mining Company was involved in a far-reaching law suit which effectively ruled that mining (subsurface) claims trump surface ownership. It is not clear whether the mine at Mercury and Jackson figured in the case, but it was a suit between surface owners in the Butte Townsite and the Silver Bow Mining Company (reported in Montana, its story and biography, by Tom Stout, published 1921 by American Historical Society, p. 427).
Another tidbit from this neighborhood (such as it was) is the location of the “Old Jail” in the middle of the block along Jackson between West Park and West Galena. The large building on the west side of the street measured about 50’x25’ and had a fenced jail yard, two small outbuildings, and a stable. The “new” jail would be the one located in the city hall that had just been erected in 1884 (today’s Jail House Coffee). The jail in the basement of the second city hall (24 E. Broadway) was the third jail, built and in use in 1890.
Note: I’m not including an illustration from the map because the Sanborn folks claim copyright to their online versions of the maps. While one might make the case that something created in 1884 is out of copyright, I’m honoring their claim based on the additional creativity they have in the online versions.
