2018 Map of Alta Creek

About this map

Thunder Basin National Grassland dominates this portion of Converse County, where the landscape is defined by the ephemeral drainage patterns of the high plains. The Dry Fork Cheyenne River winds across the southern reaches, joined by Alta Creek near a series of unnamed reservoirs and stock ponds. This era of the grassland's management is characterized by a patchwork of public and private holdings, visible through the sectioned grid lines that traverse open terrain like Dilts Flat. To the northeast, the topography becomes more pronounced at Calamity Gulch and along Lonetree Cr. The presence of numerous small water catchments and winding creeks like Bear Cr suggests a region heavily utilized for livestock grazing within the vast, protected federal range.
