About this map

The Colville Indian Reservation encompasses this high-altitude terrain in Ferry County, where the landscape is defined by the prominent Oregon City Ridge and various mountain peaks such as Bitterroot Mtn and Carson Mtn. This 1985 survey captures the area's hydrology and recreational development centered around North Twin Lake and South Twin Lake. Drainage patterns for the region are established by several watercourses, including Lynx Creek, Beaver Dam Creek, and Granite Creek.

Infrastructure is sparse, characterized primarily by Wilmont Creek Rd and a handful of local facilities. The presence of the Rocky Point Campground and multiple areas labeled Trailer Park near the lake shores suggests a seasonal and recreational focus for the community. Resource extraction is noted by several Borrow Pit locations, reflecting the ongoing maintenance of local roads and remote mountain access points during this era.
