Government Flat and Thousand Acre Pasture define the high plateau landscape of this portion of Wasco County during the mid-1970s. The map illustrates a transition from the forested heights of the Mount Hood National Forest boundary to the industrial and agricultural fringes of the Columbia River gorge. Civic and utility infrastructure is prominent, including the Grange Hall and the Chenoweth Air Park, alongside significant water management features like Wicks Reservoir and its associated Filtration Plant. This era shows a landscape being actively shaped by mid-century engineering, evidenced by the Gaging Station on Brown Creek and the Radio Facility near the Lookout Tower on Vensel Butte. Local history is preserved in the location of Indian Hollow and a local Cem near Threemile Creek, while the presence of Suicide Grade suggests the challenging topography of the region's early road network.
