2011 Map of Phifer Creek

About this map

The Middle Fork Boise River serves as the central drainage for this section of Idaho’s interior, where the Middle Fork Rd provides the primary access route through a network of steep canyons and creek beds. This landscape is defined by its drainage basins, including the extensive Phifer Creek system and the Black Warrior Creek drainage. A notable point of human activity in this isolated terrain is the Weatherby-US Forest Service Airport, located near the confluence of Fly Creek and the main river. Smaller tributaries like Steel Creek, Lake Creek, and Swanholm Creek branch out from the river valley, illustrating the complex hydrology of the Boise River basin. The map captures a moment in the early 21st century when these remote Forest Service lands remained focused on waterway management and limited aviation access.
