The northwest limb of the anticline is bounded by the North Como fault; a high-angle reverse fault. The exposed beds on the north flank are nearly vertical with some beds overturned in places. The resident bed of the Muddy Sandstone forms a northeastward-trending, well defined minor hogback that lies at a lower elevation than Como Ridge.Mudstone. Mudstone, a type of mudrock, is a fine-grained sedimentary rock whose original constituents were clays or muds. Mudstone is distinguished from shale by its lack of fissility (parallel layering). [1] [2] The term mudstone is also used to describe carbonate rocks ( limestone or dolomite) that are composed predominantly of carbonate mud. [3]

The lowest, sixth Muddy sandstone is fluvial in origin, and the overlying fifth sandstone is a transgressive marine deposit. The fourth zone represents a fluvial origin below to shallow marine above. The third zone is interpreted to be of fluvial-overbank origin with possibly a bay-lagoonal association.Abstract.
