Friday fauxld: concentric weathering rinds

Posted by Callan Bentley

Here’s a deceptive Friday “faux”ld I saw last week on the South Page Valley Road whilst learning about the Martinsburg Formation outcrops there:

Looks like an isoclinal fold in this slab of siltstone, but the curvy lines are just concentric weathering rinds. Not a real fold at all!

I hope everything you see this weekend is more straightforward and less deceiving. Happy Friday!
