2020 Map of Madison Arm

About this map

Madison Valley serves as a focal point for this landscape where the high plateau meets the waters of Hebgen Lake. The terrain is defined by the prominent Madison Arm and South Fork Arm, separated by the heavily forested slopes of the Gallatin National Forest. Along the northern shoreline, features like Edwards Peninsula and Slushers Point mark the transition from water to timbered heights. The map reveals a high concentration of springs, including the distinctive Black Sand Spring and numerous numbered hydrographic features such as 13S05E32CBDC01 Spring.
