The Black Hills National Forest landscape shown here reflects a mid-century period of significant hydraulic transition. The most striking development is the Pactola Reservoir, noted during its filling phase with a marked under construction road nearby and specific data for the normal elevation and spillway. This massive project transformed the upper Rapid Creek valley, where the small community of Silver City and the historic Canyon City are situated.
