3.5 miles, +800, - 1,500 ft ft from Trail 562 Junction
I activated this on the 13th day of a 15-day backpacking from the Elk Mountain Trailhead, via Mink Ridge & Marten Creek with a side-trip up Marten Creek to Marten Hot springs; but the route description is the more direct route across Goat Creek and along the Square Rock & Moose Ridge.
