About this map

Big Snowy Mountains dominate the landscape in this high-elevation terrain within the Lewis and Clark National Forest. The map centers on the dramatic ascent to Jump off Peak and Lime Cave Peak, where the jagged topography creates a natural watershed for several branching drainages. To the south, the sharp profile of Knife Blade Ridge forms a significant barrier above the headwaters of Careless Creek.

Logistics in this wilderness are defined by an extensive system of Pack Trails, which provide the primary means of navigating the steep canyons such as Green Pole Canyon and Black Ridge. The absence of roads underscores the area's isolation during the early 1970s. Key water features like Crystal Cascades and various named springs highlight the hydrology of these limestone-rich peaks, while the county line between Fergus Co and Golden Valley Co cuts across the southern ridges.
