Bentleyville and Marianna anchor this portion of Washington County, reflecting the industrial and residential patterns of southwestern Pennsylvania at the start of the twenty-first century. The landscape is marked by its mining heritage, specifically at Mine 51 and the associated Mine 51 Pond near the northern edge of the sheet. Resource management is evident through the series of reservoirs and dams, such as the Cokeburg Water Supply Dam and Somerset Number Sixty Dam, which define the local drainage basins of Pigeon Creek and Tenmile Creek.
