$\begingroup$ Laguna Beach is in Orange County California. I did a little research on this rock, it's basalt. I'll try the vinegar. $\endgroup$ – Herb May 5 '18 at 12:56

$\begingroup$ If I would guess I would suggest that the rock is likely a granite, there are many varieties. The color and what I suspect are crystal grains in the picture suggest that the rock is a Felsic rock, where some of the mineral crystals of unevenly weathered out. en.wikipedia.org/wiki/Felsic. $\endgroup$ – Friddy May 7 '18 at 18:32
