Lake Arthur dominates the northern half of this landscape, its irregular fingers and coves formed by the Moraine State Park Dam. Established within the expansive Moraine State Park, the reservoir has altered the local geography, submerging older valley floors while preserving the higher elevations where the borough of Prospect and the settlement of Isle remain. The map captures a moment when recreational infrastructure, such as Camp Lutherlyn and various park facilities, coexists with the area's agricultural and genealogical foundations.
