Another Anti-geocaching Article in General geocaching topics Posted February 14, 2005 Hello, I am in the cultural resources business, and what Mr. Donnelly seems to be describing is a Traditional Cultural Place or TCP. These spaces are indeed sacred, and protected under federal law, insomuch as the government has to take them into account if there are buildings or other projects that would somehow mar them. There is a lot of play in the law here, however, as these spaces might include a river, a mountain, a hill, or a rock. There would be no way for geocache approvers (or hiders for that matter) to know if a property where a cache was located was included in a TCP. These places are often secret for this type of reason, so they don't get written into guide books. If this was written up in the guide book as a sacred space, the Native Americans in question should take it up with the guidebook writers. As an archaeologist, I do have some concerns about cachers and archaeological sites, but I have found most of the caches near sites, have already been looted.
