About this map

Ninemile and twelvemile markers define the sparse prairie landscape of eastern Colorado on the Morgan and Adams County line. This mid-1960s survey reveals a landscape organized by straight-line section roads like Ninemile Road and Sherman Street, cutting across the natural drainage of Badger Creek and Sand Creek. The presence of Adena Station and infrastructure such as a Gasoline Plant, Storage Bins, and multiple pipelines highlights the area's mid-century role in energy and agricultural transport. To the west, the terrain shifts into the broken draws of Adena, where the Rosener Reservoir and a prominent Arroyo provide essential water management in an otherwise arid region. These features, captured during the 1965 field check and updated with 1980s aerial data, document the persistence of high-plains ranching and resource extraction.
