About this map

The Continental Divide serves as the high-altitude spine of this landscape, separating the headwaters of the Flathead National Forest to the west from the Lewis and Clark National Forest to the east. This 1968 field survey documents a high-country wilderness area anchored by the Bob Marshall Wilderness. Navigation through the steep drainages depends on established routes like the Gateway Trail and various pack trails that connect the Gateway Cabin to high passes and peaks.

Prominent summits including Mount Patrick Gass and Mount Drewyer dominate the horizons above complex water systems like Middle Fork Birch Creek and Spike Creek. The map captures the remote character of the Flathead and Teton County border before modern development, where the terrain transitions through the Gateway Gorge and across the Big River Meadows. It is a detailed record of the drainage patterns and ridgelines that define this portion of the northern Rockies.
