2018 Map of Colby SW

About this map

The N Fork Solomon River and S Fork Solomon River headwaters define the drainage patterns of this High Plains landscape southwest of the regional center. This 2018 survey illustrates the geometric precision of the Public Land Survey System, where a rigid grid of county roads, including Co RD 9 through Co RD 15, partitions the shortgrass prairie. The northern edge of the map is dominated by the modern transportation corridor of Interstate 70 and U.S. Route 24, which bypasses the natural contours of the intermittent Prairie Dog Cr. The terrain reflects the transition from agricultural tablelands in township t8s r35w to the more dissected breaks near the river forks, offering a clear record of contemporary land use and hydraulic features in Thomas County.
