2018 Map of Mercer Draw

About this map

Mercer Draw and its complex network of ephemeral waterways define this corner of Niobrara County, where the high plains terrain is sculpted by the intermittent flow of Lightning Cr and Twentymile Cr. The landscape is etched with the drainage patterns of Little Cow Cr and Walker Cr, reflecting the region's ranching and resource-based economy. Modern infrastructure is sparse, characterized primarily by Lightning Creek Rd and K-Field Rd, which provide access through the sprawling sections of the Public Land Survey System. This survey shows the region as it appeared in 2018, documenting the critical intersection of water drainage and land management boundaries in Wyoming's eastern plains.
