In some localities, the solution of “What to Do with Them” has been to incorporate them into a local public square or garden designed around them, such as the erratic stone in this photo from Geneva. In fact, Ryan Thompson, an artist combining the geologic within his creations, has documented many erratics into an exhibit of stereo-paired photos that seem, well, to “wriggle” uncomfortably within their present setting (see them dance at: http://tinyurl.com/o9qzovx). In a way, this is exactly what erratics look like to passing geologists – rocks that are not at all comfortable in the geologic setting where a glacier has dumped them.
Here in Greece, our glacial erratics are blamed as being off-target stones thrown by the titans from the top of Mount Ossa at their enemies, the Olympian gods. Since the type of rock in the erratic can be traced back to its point of origin, and since so many glacial erratics in Greece do seem to trace back to the Ossa-Olympos formations, then the myth must be true, right?
Either that or those erratics are doing some amazing dancing on their own when under the influence of glaciers…
