1970 Map of Sulphur Lake

About this map

Washtucna (Depression) Coulee dominates the southern landscape of this 1970 survey, where the Union Pacific railroad tracks follow the low-lying terrain. The map details a specialized agricultural and industrial corridor focused around Sulphur Lake and the small settlements of Sulphur and Estes. Multiple Grain Elevator sites and Borrow Pits along the rail line underscore the region's reliance on both shipping and local extraction. To the north, the terrain shifts into the higher ground of Michigan Prairie, deeply incised by drainage features like Rattlesnake Canyon and Sand Hills Coulee. This transition from the flat coulee floor to the rugged uplands is marked by a network of rural routes, including Lone Star Road and Lauer Road, which connected scattered homesteads and points of interest like Mc Nicholas at the start of the decade.
