1966 Map of Warren Bridge

About this map

The Green River carves a winding path through this corner of Sublette County, defining the western topography as it flows toward the Narrows. In the mid-1960s, the landscape was a blend of natural waterways and intentional water management, visible in the extensive irrigation network of the Canyon Ditch and the proximity of the Franz Reservoir. Human activity is centered around the river and its tributaries, notably near the Horsefly Campground and the Gaging Sta Warren Bridge, a vital point for monitoring the basin's hydrology.
