Lone Pine Fault Scarp | Drone Footage 

Funny you should mention, because at first I was bummed you could see my car/me, but after I edited it I thought the same as you: great for scale.

Absolutely! I can spend days in Owens Valley.

I like your thinking. Since this is the western edge of the basin and range province, my guess is there was more dropping of the floor of the valley along a normal fault than uplift of the range.

@@geologicallyspeaking Last May I drove right up to the fault scarp in my truck; the video is superb but still doesn't do justice to just how big this scarp is when standing on either side of it. Simply remarkable, especially considering that there are escarpments from that earthquake that run up the entire length of the rupture -- 50 _miles_ north of there. Everything I've read - and my way of thinking - leads me to the conclusion that this break was a _combination_ of Basin & Range extension AND glacial rebound. The Sierra Range IS rising at the same time the horsts and grabens are pulling apart; the latter instance, I'm guessing, eased pressure on the Sierra range to allow it to increase uplift in the absence of the weight of thick glaciers pressing down on the fault block. So.....I think it's safe to conclude that in the 1872 quake the Sierra fault block _rose_ as the graben _sank_ through normal faulting. Both occurred.

Great observation! There are rocks on either side, but they are covered by finer-grained alluvium. The fault cut right through an alluvial fan and the vertical displacement (fault scarp) exposed the boulders that were buried below.

@@geologicallyspeaking Wow thanks! Makes sense. So there's lots of underground boulders on the Owens Valley floor? Glacial action brought them there, correct?
