Land Classification And Density of Standing Timber - South Dakota Black Hills Forest Reserve Deadwood Quadrangle
From a series of maps done at the end of the 19th century that looks at forestation as well as agricultural lands throughout the West. It's color coded to show several qualities of merchantable timber, as well as "scattering timber" and "areas cut over". This map focuses on the area from roughly Spearfish and Sturgis, south to the small towns of Mystic and Lookout, and beyond.
Condition is very good. Image size is approximately 12.75 x 19 (inches)
