(Found this in the drafts, it must be a decade old at least.)

The drive to Lake Hughes via San Francisquito Canyon Road took a helluva long time but was gorgeous and great sight seeing with amazing roadcuts…man, the fault has done some  terrible things to those rock layers. Some were busted into fragments and frozen in place and solidified. All this incredible, slow motion tectonic violence, immense layers of rock ground to particles, destroyed. Who knows what they were, islands, maybe, they think California is the result of islands, small little land masses all smooshed together at the edge of the North American craton. A zillion  faults run through everything, Los Angeles shakes, makes us all nervous, things fall over and break. Oh well.
