Rock or Ice Cream? Erosion Tales

I’m fascinated by erosion patterns in rock that make solid rock look like ice cream that has been scooped with a spoon or carved with a giant fork. So, I was transfixed by this “fork action” on the red rock in Sedona.

Seeing this horizontal pattern in the sandstone along Oak Creek made me wonder how Nature made this carving. So I asked my geologist friend, Steve Austin. Location: West Fork Trail, Sedona, AZ, USA.

It’s amazing what Steve can tell us just by examining this photo and knowing its location. He said, “The sandstone has horizontal layers but also has inclined layers internally (25 degrees). The cliff shows these inclined layers because rockfall has sculpted the surface. These inclined layers were formed in underwater sand dunes by flow velocity of 2 meters/second.”

Wow! That’s why they call Steve “Mudflow Man.”
