The settlement of Valmont and the surrounding Boulder Valley landscape appear here at the start of the 1950s, defined by a complex web of agricultural irrigation and industrial development. The Colorado White Rock and North Boulder Farmers Ditch and numerous other waterways like the Mc Ginn Ditch illustrate the engineered hydraulic network that supported local farming. Near the Valmont Butte, industrial sites such as the Fluorspar Mill, a Brickyard, and a Power Plant highlight the area's mid-century economic activities.
