In honor of Earth Day on Saturday, April 22, Volunteers for Outdoor Colorado will be working with the City and County of Denver and the Rocky Mountain Arsenal National Wildlife Refuge to construct 6,600 feet of new trail along First Creek. Volunteers ages 10 and up will build the trail by hauling and spreading an aggregate material known as "crusher fine." Tasks will be easy-to-moderate in difficulty. The Refuge's eastern boundary is accessible to numerous local residents but has few amenities. Now, you have the opportunity to help the area become a valuable open space where thousands of people can gather, play and experience Colorado's great outdoors!
