Leave natural and cultural artifacts. Natural objects of beauty or interest, such as antlers or mineral crystals, should be left alone for others to discover and enjoy. In national parks and some other areas it is illegal to remove natural objects, or to do so without a permit.
Archaeological, cultural and historic artifacts preserve an important part of our nation’s past. Some artifacts and locations are sacred to Native Americans, others may contain clues to the past that a historian can help us interpret.
