Friday fold: Miocene slump in Anza-Borrego
Posted by Callan Bentley
Today’s Friday Fold comes from Edith Carolina Rojas, the dynamic geology professor at The College of The Desert in Palm Desert, California. She’s an awesome person, and also the sense of scale in this amazing image:
Edith shares that this gorgeous structure is an
anticline is located in Split Mountain Gorge in Fish Creek Canyon. It’s a gigantic gravity-slide fold due to soft sediment deformation in the Latrania Formation.
Wow – Great stuff. I’d love to see this site in person someday!
What characteristics of this anticline indicate that this is gravity-driven soft sediment deformation from a slide versus an anticline in more competent rocks? Is it the lack of organized fault planes and slickensides?
