Geo 730: July 5, Day 551: Auntie Kline II

A close-up of the anticline in the previous post. Part of the reason I suspect this was "semi-soft" deformation is that the rock does not seem to be metamorphosed at all... the mud layers are quite friable. If this had been subjected to enough heat and pressure to plastically deform the rock, I'd expect the fine-grained portion, at least, to show some signs of that.
