The ice caves on Allagash Lake are part of the "Unique Natural Areas" on the DeLorme's Atlas. If an earthcache was placed there, there would be nothing physical at the site. They can't argue that hordes of cachers will defile the area, it's hard to get to, and already publicly listed on the Atlas for people to visit.
It certainly wouldn't be the 'drive-by' that the former virtual was, but it would serve as a map 55 cache.
