These are the cliffs off the Dana Point headlands. The headlands are home to a nature preserve plus a few very expensive homes. The cliffs themselves aren't normally ruddy red except for a few minutes near sunset, which just happened to be exactly when I was there.

I saw a photo of some cliff edge Dana Point homes looking to take the plunge into the ocean.
How do we know those aren’t the Cliffs of Dover that have been photoshopped?
Late day / early morning shots are the best, aren't they?
The Sandia and Manzano Mounains near Albuquerque do the same thing in the right seasons. That's why they were named for watermelons and apples.
Bah. Clearly it is Ayers Rock after sea-level rise…
I can almost feel those clouds move.
