Just a couple corrections. First, you can no longer access Kenwood Blvd from the 15N since the interchange update - there is a wall that keeps you from moving to the exit. You have to travel south on the 215 for a moment and exit into Devore there, where you can now travel the newly reconnected portion of old Route 66 north. Second, the animation that shows that the fault has had a purely linear affect on the terrain isn't quite right. I can't find a link to it, but the animation I've seen shows that the San Bernardino Mountains not only have slid along the fault, but very large blocks of the mountain range are surmised to have rotated, like a the rollers under a conveyor belt, as the plates pass by one another. After seeing this on PBS some time ago, I'm not seeing much mention of it online today. Makes me question if it's still the currently theory.
Otherwise, excellent video. This guy does a great job visually relaying information. His video on the cajon pass is good too.
