Friday fold: soft sediment deformation in California’s Castaic Formation
Posted by Callan Bentley
The Friday fold comes to us today from Bret Leslie of the Nuclear Regulatory Commission, a friend through the Geological Society of Washington. It shows soft sediment deformation in the Late Miocene Castaic Formation, a unit deposited in the Ridge Basin, a wrench basin that opened in a releasing bend along the San Andreas Fault:

Thanks for sharing, Bret!
If you have a Friday fold you’d like to share, get in touch with me.
Should be “Castaic”, not “Castiac”.
Many thanks – I propagated the typo from the Earthcache webpage to this post. It’s corrected now.
How exciting, however it’s spelled.
How do I submit a “Friday Fold’ photograph?
