SBTS Trail Crew Finishes the New Acorn Grotto Trail on Mount Hough

The Sierra Buttes Trail Stewardship Pro Trail Crew reached a big milestone last week, punching through the new 3.6-mile Acorn Grotto trail on Mt. Hough to connect with the 25N14 doubletrack Quarry Road, about halfway up MT. Hough (See Trail #10 on the map), after several years of work. The crew is now working to finish Trail #8—when that’s opened, it will establish a new top-to-bottom singletrack route from Indian Falls Ridge at the 7,200-foot summit of Mount Hough and a new Yuba Expeditions shuttle option to boot: 17 miles from summit to the swim hole!
