2011 Map of Sphinx Mountain

About this map

Sphinx Mountain and Pioneer Mountain dominate this high-elevation landscape in Madison County, where numerous drainages carve through the Madison Range. The drainage patterns revealed here show a complex watershed including the South Fork West Fork Gallatin River in the north and the southward-flowing Indian Creek. Remote outposts such as Manley Camp and Indian Crossing provide evidence of human activity in an area otherwise defined by its sharp peaks and deep basins, such as McAtee Basin. A network of Forest Service routes, including FS 531 and FS 325, snakes through the eastern portion of the quadrangle, primarily following the courses of Second Yellow Mule Creek and Third Yellow Mule Creek. Notable landmarks like Eglise Rock and Flattop Mountain serve as distinctive navigational points within this wilderness, which remained largely undeveloped well into the early 21st century.
