ROCK RIVER CANYON WILDERNESS STUDY AREA, MICHIGAN.
January 1, 1984
A mineral survey of the Rock River Canyon Wilderness study area, Alger County, Michigan, concluded that there is little promise for the occurrence of metallic mineral resources in the study area. High silica sand and crushed rock from quartzose sandstone that is bedrock for much of the area occur but are available in more accessible areas outside of the wilderness.
