About this map

Diorite and the adjacent settlement of Snowville anchor the southern portion of this landscape in Marquette County, Michigan. This region is defined by its complex hydrology and history of resource extraction, illustrated by the presence of Gold Mine Lake and Gold Mine Creek. The industrial heritage of the area is solemnly marked at the Barnes - Hecker Mine Memorial Cem, a site of significant local historical importance. Northward, the terrain is dominated by the Dead River Storage Basin and a network of drainages including Barnhardt Creek and Second River. Transportation routes like Blueberry Mine Rd and Diorite Rd suggest the enduring connection between these remote settlements and the mining operations that historically sustained them, while numerous small lakes such as Boston Lake and Brocky Lake dot the forested interior.
