About this map

Markle Pass serves as a geographic focus in this section of Northwest Montana, where the Salish Mountains meet the northern edge of the Camas Prairie Basin. The landscape is defined by its dramatic elevation changes, rising from the basin floor toward Schmitz Mtn and the surrounding peaks. A network of rural roads, including Little Bitterroot Rd and Wilks Gulch Rd, connects the scattered water features of the region, from the Little Bitterroot River in the east to the Schmitz Lakes tucked within the central slopes.

Evidence of early 21st-century infrastructure and land management is visible through the presence of the Hot Springs Airport and the clearly marked Markle Cem near the western pass. The topography is deeply carved by drainage systems like Wilks Gulch, Big Gulch, and Warm Springs Cr, which illustrate the complex watershed feeding into the valley floor. This survey documents the boundary between Sanders and Lake counties as it crosses these ridges and gulches.
