The South Platte River carves through this landscape at the edge of the Pike National Forest, defining a region of hydraulic engineering and industrial transition in the mid-1960s. The town of Kassler serves as a hub for water management, situated near the Filtration Plant and the High Line Canal, while the massive Aurora Rampart Reservoir sits perched above the Hogback formation. To the north, Waterton marks the entrance to the South Platte Canyon, a critical corridor where the river meets the plains.
