The San Juan National Forest has joined with the local community to help celebrate the 50th Anniversary of the Wilderness Act. The 2 mile Wilderness Walk will begin at the La Plata County Fairgrounds at 9 a.m., follow the Animas River Trail to Rotary Park and loop back to the Fairgrounds. Participants will receive a commemorative pin and branded wood chip celebrating the anniversary. There is no need to register in advance. Family Fun Fair booths and activities will begin at 10:30 a.m. with music provided by the San Juan String Band. Activities will include a Kids Education Corner and demonstrations of stock packing, primitive tool use, backcountry gear, low-impact river camping and Dutch-oven cooking techniques. There also will be a wilderness backcountry cooking contest. The walk and activities are free, but food and beverages will be for sale. For more information, call Kathe Hayes at 385-1310.
