2020 Map of Petty Mountain

About this map

Lothrop sits along the northern edge of this map, situated in the corridor where the Clark Fork river and Hwy 10 cut through the mountains. This 2020 survey reveals a landscape largely defined by the Lolo National Forest, where steep drainages such as Tucker Gulch, Madison Gulch, and Spring Gulch feed into the south-running Petty Creek. The terrain rises sharply toward the Grave Creek Range and the summit of Petty Mtn, which towers over the southeastern portion of the quadrangle. In the lower elevations, modern residential road names like Cinderella Ln and Terrace View Dr indicate contemporary development near the river, contrasting with the remote forest roads such as Printers Creek Rd and Outback Trl that penetrate the high country. The map also captures the Moulton Reservoir Number Two, a small water body tucked away in the southern reaches of this mountainous terrain.
