Geo 730: November 26, Day 695: School of Hard Knocks

Looking over later photos of this outcrop, I found I'd misremembered it somewhat in yesterday's description- it appears to be a lava flow- likely andesite or similar- overlain by lahar deposits, not simply piles of those debris flows. However, there's still plenty of bouldery, loosely consolidated and poorly sorted debris up above that andesite (?) cliff, and pieces obviously fall out and off frequently. This poor, beaten up Jersey barrier testifies clearly to that.

Photo unmodified. October 10, 2012. FlashEarth Location (possibly maybe).
