Rocks at Dawn!

Busy busy busy!  Just a quick post with some more pretty pictures from out west...let the glow of dawn light on the fluvial/alluvial Cathedral Bluffs keep you warm on these wintery days!


Interbedded sandstones (of both the channelform and sheety variety) are dominantly white, though up-close inspections reveal a fair amount of lithic fragments, including sed rocks and feldspar rich igneous chunks.  Reddish, laterally extensive silt-rich mudrocks make up the rest of this succession.


Happy Thanksgiving Eve!
