Trail Safety: Follow Posted Rules The trail is covered by a thick layer of asphalt, and gravel barriers placed along it isolate mining contaminants. While EPA has determined that using the trail is safe, trail users must be sure to follow all trail-use rules (see below) and posted signs, including directions to stay on the trail in rural areas. Following the rules will help people avoid places with mining contamination and private properties next to the trail. Stay on the trail. Wash hands and face before eating. Eat at designated waysides and trailheads. Remove dirt from clothes, toys, pets, shoes, and equipment before leaving the area. Don’t let children play near shorelines or off the trail. Carry water for drinking and washing. Motorized vehicles are prohibited.
