Cascade Canyon
Posted by Callan Bentley
Following up on Friday’s fold, I wanted to share a few other images from our hike last week in Cascade Canyon of Grand Teton National Park. Lots of cool exposures of Archean basement rock there.
Folds in gneissic banding:
Big, angular mafic blocks in a felsic soup:
Swarm of granite dikes on a mountainside:
Asymmetric feldspathic porphyroclast in amphibolite, with apparent reaction rim:
Boudinage and an isoclinal fold:
Ptygmatic fold:
A nice series of cross cutting relationships:

Great pictures!
I think a velcro covered vest would be a great idea, in the best NASA astronauts style. Problem, it would catch so much dirt and flowers that you would look like a Christmas tree after 10 minutes in the field.
Uhm… perhaps I patent the idea and I just sell it to some naive mining engineer!
