About this map

The Tobacco River and its associated tributaries dominate this Lincoln County landscape, defining the hydrology of the Tobacco Valley south of the Canadian border. The map documents a complex system of glacial kettle lakes and drainages, including Othorp Lake, Thirsty Lake, and Alkali Lake, which sit between prominent rises like Black Butte and Eureka Hill. These water bodies and the surrounding timberland have long supported both recreational and industrial uses, evidenced by the Rock Lake Campground and the Luman H Bradburn Mine.

Logistics in the area are anchored by forest and county roads such as Pinkham Rd and Othorp Lake Rd, which provide access to the various draws and gulches. The terrain transitions from the river bottom up toward Virginia Hill, while southern drainages like Pinkham Creek and Cooks Run carve out the southern reach of the quadrangle, illustrating the diverse topography that characterizes this portion of northwest Montana.
