With Libby Gans, I wrote Roadside Geology of Southern California, published by Mountain Press Publishing Company, Missoula, Montana, January 2016. 

With Allen Glazner, Robert Sharp, and Libby Gans, I worte an updated, revised, and colorized 2nd Edition of Geology Underfoot in Southern California, published in April 2020 by Mountain Press Publishing Company, Missoula, Montana

I maintain low level monitoring of erosion and retreat of the UCSB beach cliffs.
