All this time and no guesses.Wave Rock in Australia.
ATTABOY frethackGrandfather Mountain, in northwest North Carolina it is. Callaway Peak on the Mountain is the highest peak along the Blue Ridge.The mountain is a major tourist attraction- you can drive to the top and hike over the mile-high swinging bridge. Also home to the largest highland games in North America (and I've been told 3rd largest in the world, but would have to check this more thoroughly).The "window" exposes Grenville age metamorphic rocks below the Appalachian thrust block. There's even some small, high-grade gold deposits on the mountain.Several years ago, geologists found parallel etch marks on some of the exposed rocks and suggested they were evidence of past glaciation (scour marks). Turns out they were made by log chains hauling timber over the rocks at the turn of century.
Welcome back Bass!Metamorphic rocks over a billion years old would probably be Grenville in origin. The Ouachitas are mostly absent of metamorphism, from my understanding anyway, so my guess would be that these mountains are probably Appalachian (IF theyre located in the States that is).Just trying to narrow my search a little...am I getting warmer?
(the Ouachita's have a distinct metamorphic section, even in outcrop, although the outcrop is medium grade at the highest. the subsurface has very high-grade metamorphics, including probable Cambrian-Ellenberger) marbles.
right hemisphere, wrong continent- are there seals in Loch Ness? (I assume Nessy would've consumed them long ago)
