Billy Goat Trail photos by Luke O'Neil
Here's some photos from today's Physical Geology class field trip to the Billy Goat Trail. It actually snowed on us a little bit... cold! My student Luke O'Neil took all of these, hosted on his Facebook page, and this is an experiment to see if I can post Facebook photos on my blog... keeping my fingers crossed...
Migmatite:
Il profesore showing tilted tree trunks (knocked in a downstream direction during floods):
Folded graded bed in metagreywacke:
Students circle around an exotic boulder of the Catoctin Formation greenstone (from the Blue Ridge province); the boulder was transported downstream by the ancestral Potomac River when it was flowing on the Bear Island strath, before incision and abandonment of the former river bottom to become a bedrock terrace:
The difference between fresh (right) and weathered (left) metagreywacke:
Great Falls with lots of water flowing over it:
Thanks to Luke for sharing these photos!

Your welcome. I am going to try and get some pictures from the videos I took. I will post them on my facebook page and on the photobucket page I made, http://s728.photobucket.com/albums/ww285/geologybillygoattrail/.
