The South Platte River carves through the foothills of the Pike National Forest, defining a landscape where industrial infrastructure and recreational wilderness meet. The settlement of Kassler sits near the mouth of Platte Canyon, just downstream from the Platte Canyon Reservoir and the start of the Highline Canal. This area serves as a critical water management corridor, evidenced by the Aurora-Rampart Reservoir and a massive treatment plant located near the community of Roxborough.
