2011 Map of Blackleaf

About this map

The Blackleaf area of Teton County is defined by its extensive network of water management and deep coulees carved into the Montana landscape. This 2011 survey illustrates a region where ranching and agricultural operations depend on a series of small-scale infrastructure, including Decameter Dam and the uniquely named Decarboxylation Dam. The drainage pattern is complex, with the South Fork Dry Fork Marias River and the Middle Fork Dry Fork Marias River cutting through the northern reaches, while Blackleaf Creek and Muddy Creek wind through the southern sections. Family and place names are etched into the topography through numerous coulees, such as Ben English Coulee, Woods Coulee, and Gansman Coulee. This map documents the rural road network connecting these remote sites, featuring W Gypsy Basin Rd and Blackleaf Rd, providing a clear record of the area's contemporary land use and hydraulic engineering.
