The eastern front of the Rocky Mountains defines this 2019 survey, where the high-altitude landscape meets the urban edge of Boulder and Arvada. This section of the Roosevelt National Forest is characterized by dramatic geological formations, notably The Flatirons, Royal Arch, and South Boulder Peak. The interface between nature and infrastructure is evident in the presence of Gross Reservoir and the Aqueduct system, while the BNSF Railway winds through the steep terrain near the Boulder and Jefferson County line.
