Re: Beautiful...Beautiful picture, indeed. What kind of force did it take to lift those sedimentary layers halfway to vertical like that?

Re: Beautiful...Larry, I don't know the geological history on The Fortress, but am adding one I climbed on Wednesday, Ishbel, that was undercut severely by a massive slide causing it to lean.....the ridge crest itself was so hollow, we finally begged off to a ramp up the side to the final summit...then got buzzed with the pre-lightening jitters....our helmets were live! Should get it added tomorrow...never been on a mountain so compromised from the bottom up...cheers!!

Re: Beautiful...The dip of the the beds is the result of regional faulting and folding during the mountain building process - all powered by the movement of plates in the earth's crust.

Canadian Rockies specific
It shouldn't be, but it seems hard to find a good illustration of how folding and faulting occur together HERE is a cross section showing a folded faulted and eroded mountain range. Click on Complex folds and faults.
