I activated this on the 12th 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 ridge that we took on our way out.
