2019 Map of Rock

About this map

Rock and the surrounding timberlands of Delta County are documented in this 2019 survey, illustrating the persistence of rural communities in Michigan's Upper Peninsula. The landscape is defined by the headwaters of multiple river systems, including the Rapid River, Days River, and Tacoosh River, which weave through the townships alongside smaller streams like Mud Cr and Indian Cr. These waterways historically drove the regional economy and continue to shape the layout of local roads such as Days River Rd. Settlement patterns remain concentrated around the small village centers of Trombly and Campbell. Local heritage is anchored by sites like Rock Cem and Maple Ridge Cem, while the grid of farm-to-market roads, including W Maple Ridge 37th Rd and Finn Hall 38th Rd, reflects the agricultural and residential development of Maple Ridge Township.
