    Description

    LAST ONE!!!
    This is
    USGS Bulletin 1042-E, “Physical Stratigraphy of the Phosphoria Formation in Northwestern Wyoming.”
    Published in 1957, this is a scarce report on this geologically interesting area. This 80-page book comes complete with all five sheets in a pocket in the back of the book. It discusses this important formation that is widespread around the northern Rockies states. The Phosphoria is important for numerous mineral deposits, and as the source of Turritella stone, which is that agate-like rock that has hundreds of snail fossils in it.
    The correlation diagram (fourth photo) is a masterpiece of geology.
    This report provides a unique geologic perspective on this formation that few other reports do.
    I will continue to add new items to my store, so check back periodically.
