1966 Map of Greystone Butte

About this map

Weir Creek Hot Springs sits along the northern banks of the Lochsa River, highlighting a remote corridor where thermal activity and steep drainages meet. This mid-1960s survey documents a landscape defined by the transition from the Clearwater National Forest into the protected Selway-Bitterroot Wilderness. The terrain is characterized by high-elevation landmarks such as Greystone Butte and Ashpile Peak, with water flowing through complex systems like Gedney Creek and Sponge Creek. A network of pack trails provides the primary access to the interior, connecting points like the Lookout Tower at Mocus Point and the secluded Greystone Lake. The confluence of the Middle Fork Clearwater River and its tributaries underscores the significance of these waterways for travel and resource management in the Idaho backcountry during this era.
