2020 Map of Bly

About this map

The high-desert settlement of Bly sits at a critical junction where the Sprague River watershed gathers from several mountain forks. This landscape is defined by the hydrologic transition from upland volcanic features like Round Butte and Bly Ridge to the broad, marshy bottoms of Leonard Slough and Gayheart Slough. Much of the territory is managed as part of the Fremont National Forest, illustrating the region's reliance on timber and grazing lands. The map details a complex network of forest roads and irrigation infrastructure, including the N Fork Ditch and Elder Ditch, which redirect water across the flats for agricultural use. Aviation footprints are visible through Allen's Airstrip and Anderson Field, serving this remote corner of Klamath County. Local landmarks like Whiskey John Flat and The Elbow mark the distinctive terrain of the Fremont Highlands.
