Friday fold: “wrecumbent in Wrangellia”

Posted by Callan Bentley

Darrel Cowan of the University of Washington has pitched in a Friday fold. Check this lovely scene out:

Darrel says this is

a recumbent fold in the Upper Triassic Nizina and Chitistone limestones. I took the photo when I worked for Shell in 1973 or 1974. I’m pretty sure it is on the west wall of the canyon occupied by the Root Glacier, several kilometers NW of McCarthy, Alaska. The view is west. These limestones are part of the stratigraphy that defines the Wrangellia terrane: the type locality, matter of fact.

Thanks Darrel! This is inspirational!
