Deerlodge National Forest encompasses this high-altitude landscape in Powell County, where water management and mountainous terrain define the local geography. The map reveals an intricate network of historical irrigation infrastructure, including the Old China Ditch, Pauly Ditch, and the Kohrs and Helenberg Ditch, which redirect water from sources like Rock Creek to support the surrounding valleys. High-country drainage is centered on features like Rock Creek Lake and the dramatic Rock Creek Falls. Significant peaks and formations such as Pikes Peak Ridge and The Crater loom over valleys like Pioneer Gulch and Mullan Gulch. This 2017 survey documents the modern state of remote access routes like Gold Creek Lakes Rd and Old Stage Rd, which navigate the steep divide between the forest and the specialized water features like Nine Trough Spring and Dolus Lakes.
