Those could be pillows
Posted by Callan Bentley
More pillow-like structures, seen in the Catoctin Formation, on the west side of the Blue Ridge Parkway about ten miles south of Interstate 64.
Mini Sharpie for scale – what do you think? They don’t seem to be as strongly fracture-controlled as the Stony Man area “pillows.” But dang, they sure are small…
Read the context here, and then asses this new outcrop for likeliness of pillowhood.
Could they be an incipient columnar structure which has undergone some deformation and diagenetic alterations?
