Agricultural development and irrigation infrastructure define the landscape of Sheridan County on this 1960s survey. The map centers on the extensive Mirage Flats, including the West Mirage Flats and East Mirage Flats, where the Mirage Flats Canal winds through the terrain. The presence of the Mirage Flats Project Headquarters underscores the importance of water management in this portion of the Missouri River Basin during the mid-20th century. Local social centers are visible in the placement of the New Hope Ch and St Peters Ch, alongside rural education sites like Sandridge Sch and Alcove Sch. Technical details of the irrigation system, such as a Siphon and Flume, illustrate the engineered nature of the plains during this era of agrarian growth.
