More From Fingal's Cave...

Since you're all obviously fans of Weird Geological Phenomena, I thought I'd put up some more photos of Fingal's Cave.  I went for the Informative Photos this time, rather than the Strange and Atmospheric ones.  As Fingal's Cave is unfamiliar to a couple of you (the location, not the overture...)
