2017 Map of Lassen Creek

About this map

Thunder Basin National Grassland encompasses a significant portion of this Weston County landscape, where the high plains are dissected by a complex network of ephemeral watercourses. The drainage patterns of Lassen Cr and Mush Cr illustrate the subtle but essential topography of the eastern Wyoming ranchlands. The road system, including Mush Creek Rd and Howard Rd, follows the natural contours of the land, providing access to remote sections of the grassland and private holdings. Notable terrain features like Williamson Draw and Statler Draw provide historical context for the movement of livestock and early surveying efforts in the region. This 2017 study reflects the modern management of public lands while preserving the original township and range designations that have defined the area's geography since the initial settlement period.
