Lolo National Forest and Deerlodge National Forest meet in this 2017 survey of Granite County, Montana. The high-elevation terrain is defined by the John Long Mountains, where prominent landmarks like Silver King Mtn and Silver King Ridge dominate the southern landscape. The complex drainage network of the N Fork Lower Willow Cr and its various tributaries, including Eightmile Cr and Harvey Cr, suggests a watershed that has historically shaped local access and land use. Numerous gulches such as Eureka Gulch and Griffith Gulch carve the northern slopes near Harvey Point. This modern topographic study details the isolated mountain ridges and vital water sources like Barton Spring and Horsethief Spring that remain essential to navigating this portion of the forest reserves.
