I went shopping for rhyolite cabs this morning -  AND bought this tiny Thunderegg!

THE BOOK on John Day Fm. etc. Thundereggs! "Geological Survey Bulletin 1161-D 1964" I have searched for this for YEARS and could not find it. I didn't know he made it into a book! This morning I found THIS on Amazon! www.amazon.com/gp/product/1289107831/ref=ppx_yo_dt_b_asin_image_o00_s00?ie=UTF8&psc=1 Temporarily out of stock but I ordered it! Happy as a June bug in a corn field! 
I strongly disagree with his theory on T.E. Formation -
