Antlers shed by large animals are a source of minerals for smaller animals. It is illegal to remove any animal parts
from Yellowstone. Leave rocks, plants, seeds, feathers, bones and other natural substances where you find them.
Edible plants, mushrooms and berries may be picked for your daily consumption while in the Park. Make certain that
you know what plants, mushrooms and berries are edible. If you're not sure, don't eat it.
Evidence of prehistoric occupation in Yellowstone National Park dates back over 10,000 years. Prehistoric and
historic sites are found throughout the park. These cultural resources are protected by law, and it is illegal to disturb or collect things from such sites. Should
you discover an artifact or site, report it to a ranger.
