2017 Map of Blowfly Creek

About this map

Challis National Forest dominates this section of Custer County, Idaho, where the complex drainage systems of the Salmon River mountains are documented in high detail. The map centers on the high-elevation terrain between Morgan Creek and several western forks. Significant landmarks include the sharp elevation of Rye Grass Pinnacle to the east and Red Butte to the south. The area is characterized by a network of seasonal and perennial water sources, such as Third Spring and Fourth Spring, which feed into the larger creek systems.
