Entrance fee waived for all visitors Sept. 24


The National Park Service is seeking volunteers for a work project in the Mammoth area of Yellowstone National Park on Saturday, Sept. 24. As part of National Public Lands Day, the largest single-day volunteer effort on public lands, the park’s entrance fees will be waived for all visitors. 
Volunteers will participate in trail restoration across the main road from the Mammoth Campground. Work will take place from 9 a.m. to 4 p.m., and includes erosion control, obscuring and removing social trails, planting native vegetation and delineating a trail. The work is strenuous and requires the use of hand tools, lifting heavy objects, and working at high altitudes in variable weather conditions.

Drinks and snacks will be provided. All volunteers should bring lunch, water, sunscreen, sturdy footwear, and clothing suitable for a range of conditions as weather can be cold and blustery in late September.

Volunteers who participate in a National Public Lands Day activity will receive a coupon good for a one-time free entrance to the federal Public Lands Day area of their choice. Space is limited to 30 volunteers. Volunteers are asked to register by Sept. 19 by emailing or calling (307) 344-2729.
