2018 Map of Jim Jam Ridge

About this map

Trinity National Forest encompasses this wilderness area in Northern California, defined by the deep drainage of the New River and its tributaries. The landscape is marked by the high elevations of the Salmon Mountains and distinctive landmarks such as Beartooth Mtn and China Peak. Access is limited to a few specific corridors, including Miller Ranch Rd in the north and Denny Rd to the west, reflecting the area's isolation and reliance on forest service infrastructure. Several named water sources, such as Jim Jam Spring and Whisky Cr, suggest historical points of interest for pack travel and early resource management. The map details a complex system of ridges and gulches, from Bake Oven Ridge to Semore Gulch, which have shaped the movement of both water and people through this part of Trinity County for decades.
