Forty-Eight volunteers helped the City of Boulder’s Open Space and Mountain Parks (OSMP) Department improve the East Boulder-White Rock Rocks Trail on National Trails Day June 7.

The volunteers shoveled and laid down 120 tons of crusher fines filling gullies on 2,080 feet of the East Boulder/White Rocks trail, which sustained significant damage during the September 2013 Boulder floods.

National Trails Day is the United States’ largest celebration of trails, according to the American Hiking Society. During the day, organizations and groups celebrate America’s trails by organizing hikes, stewardship projects, biking and horseback rides, and other activities.
