As I commented to Larry Wilson the other day, in a few decades, it might be extremely difficult -- if not downright impossible -- to locate one or the other, or both, of these ice-cap DYE sites. Three processes apparently are at work at each site: the structures are literally sinking into the ice sheet; they are being covered over by new snow that is falling and drifting; and the ice sheets underneath them are drifting. Now, DYE-2 apparently is visited regularly by the NY-ANG, as there is a landing strip adjacent to the old radar facility. DYE-3, though, is more isolated and not visited any more (at least, not on a regular basis), so it might become "lost" first.
