Yesterday, I sailed to Santa Cruz channel island off of the CA coast. I was with a group researching an endemic fox that lives there but these oaks (and a pine) caught my eye. I'm not sure I've seen such twisted oaks.
Sorry, no leaf photos. There was another variety of ground hugging oak with very small leaves (there is a similar variety in the Sierra that is known as huckleberry oak). I would love to try to work with that.
