2000 Map of Reas Pass

About this map

The Continental Divide defines the high boundary of this landscape, marking the border between Fremont and Gallatin counties and the state line between Montana and Idaho. Located within the Targhee National Forest, the area is characterized by a network of seasonal routes and high-elevation waterways. The Continental Divide National Scenic Trail winds along the ridge, while specialized paths like the Two Top Snowmobile Trail emphasize the region's recreational use. Historical remnants are found at the Big Springs Lookout (Site) and a Comm Site, suggesting the area's importance for observation and communication in the high backcountry. Significant drainage systems include the South Fork Madison River and various canyons such as Dry Canyon and Black Canyon, which collect runoff from the surrounding peaks and the expansive Plateau to the south.
