Yosemite National Park and the Yosemite Climbing Association invite the public to participate in the “Yosemite Facelift” being held on Wednesday, September 21 through Sunday, September 25, 2010. This annual event is organized by the Yosemite Climbing Association to help clean up the park after the busy summer season. Volunteers are needed to help pick up litter at various locations in the park, including roadways, in the river corridor, on trails, near climbing routes, and in parking, camping, and lodging areas. Events and presentations honoring Yosemite’s climbing history will be held throughout the weekend. https://www.nps.gov/yose/learn/news/facelift11.htm
