About this map

Manti-Lasal National Forest encompasses the high canyon country of San Juan County, where high plateaus like North Elk Ridge drop into a labyrinth of drainages. The landscape is defined by its verticality, with prominent landmarks such as Deadman Point and Steamboat Point towering over complex canyon systems. Local water sources are rare but vital, marked by Big Spring, Sego Spring, and the high-elevation Duck Lake.

Evidence of historical range use is seen in labels like Redd Pasture and Poso Pasture, connected by primitive tracks including Redd Pasture (446). This 2017 survey details a network of named trails, from the high White Rim Trail W to the winding The Notch Trail, which navigate the deep incisions of Poison Canyon and Horse Pasture Canyon. These routes provide access to remote features like the Queens Arch and the broad flats of Sego Flat.
