Summer’s coming to a close and there’s a hint of Fall in the air so it’s time to free up a couple of hours and help clean up the Mammoth Lakes Basin!  For the last several years, the Mammoth Lakes Trail System has coordinated with the Sierra Nevada Conservancy’s Great Sierra River Cleanup to cleanup and give back to our community’s namesake, the Mammoth Lakes Basin. Please join our co-hosts the Eastern Sierra Nordic Ski Association and the Mammoth Lakes Chamber of Commerce at the Horseshoe Lake parking lot at 8:30 a.m. on Saturday, September 17 for the final Summer of Stewardship Trails Day Event of 2016.
