Geology of the Butte mining district, Montana
The Butte mining district is in Silver Bow County in southwestern Montana at the intersection of 1-15 and 1-90. The district proper lies north and west of these highways, and most of it is within the business and residential areas of Butte. Because city streets provide access to all of the stops, they are easily accessible by automobile or on foot as shown in Figure 1. The sites described lie on private land and direct access is not practical to most of them; however, because of their large size they can be easily viewed from the public right of way. A pair of binoculars is useful in viewing some of these features. Unfortunately, the best exposures of veins are in the underground workings no longer accessible or in open pits to which access is prohibited.
