Dear Mission Support,

I am in the hab. ! I continue study of the geology map. I have done rock
separation from Cretaceous Dacota Formation and Jurassic Morrison
Formation.  Base on my study I concluded that fluvial sandstone originate
from Morrison Formation and concretions in the light sandstone from
Dacota.
