Description

This trail has a few places where you can start: Pebble Creek Ski Area, Inkom Pass (via South Fork Inman Creek Canyon Trail and the Upper Jackson Creek Trail), or Big Springs Campground. The trail follows a wider track that accommodates ATVs and dirt bikes. From Pebble Creek Ski Area, the trail heads north until it crosses Jackson Creek. The trail then heads up Jackson Creek Canyon to Inkom Pass. This is a steep climb, and will probably be difficult for most people to run, but hiking is okay. The footing here is rocky in many places. From Inkom Pass, the trail drops down towards Big Springs Campground in a nice gradual drop. This section is nice and shady, passing under a lovely canopy of pines, aspens, fir, and spruce trees.

The route has signs that say "Boundary Trail 072" throughout the route, but the USFS maps label this trail the North Boundary Trail and assign the number 244 to it.
