Pohatu Nuva: Caches may be quickly archived if we see the following (which is not exhaustive):
* Caches on land managed by an agency that prohibits geocaches, such as the U.S. National Park Service or U.S. Fish and Wildlife Service (National Wildlife Refuges).
* Caches that are buried. If a shovel, trowel or other "pointy" object is used to dig, whether in order to hide or to find the cache, then it is not appropriate.
* Caches that deface public or private property, whether a natural or man-made object, in order to provide a hiding place, a clue or a logging method.
* Caches placed in areas which are highly sensitive to the extra traffic that would be caused by vehicles and humans (examples may include archaeological or historic sites).
* Caches hidden in close proximity to active railroad tracks. In the United States we generally use a distance of 150 ft (46 m) but your local area’s trespassing laws may be different. All local laws apply.
* Caches near or on military installations.
* Caches near, on or under public structures deemed potential or possible targets for terrorist attacks. These may include but are not limited to highway bridges, dams, government buildings, elementary and secondary schools, and airports.
