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

1161-d

Temporarily out of stock but I ordered it! Happy as a June bug in a corn field! (thumbs-up)

I strongly disagree with his theory on T.E. Formation -

As the volcanic ash flow tuff cooled, trapped steam and other gases formed an expanding bubble. Silica and feldspar minerals often crystallise around the bubble or grow crystal fibres which radiate outwards from the its centre. These mineral-filled bubbles with a radiating structure are called spherulites
