Calabasas is basically an area stretching from a the end of the San Fernanco valley floor but climbs into some foothills, so elevation there varies (and if Wikipedia's 928ft elevation is the usual city hall, believe that's one of the lower elevation locations there....Burbank is just about 600 feet and Van Nuys 700 feet but are much flatter than Calabasas, too. I've driven and cycled in the area, my brother works near there and his in laws live there). I searched and found something saying he crashed at 1028 ft elevation. Still, helluva rate of descent. Wonder if he was trying to follow Hwy 101 or was allowed to or....
