Description

Author: Griffitts, Mary O.  (1920-2010)

Publisher: Mesa Verde Museum Association

Pub Date: 1990

Binding:Paperback (Pamphlet)

Condition:  Good.  Binding tight.  No marks, tears, bends or folds.   Includes map in pocket at rear.  Very light edge and corner wear.  Not stated but I imagine this was the first printing.

Notes: Big surprise–marine fossils (oysters, clams, shark teeth) have been found within the Park boundaries.  “The rocks on the surface at Mesa Verde are between 78 and 91 million years old, deposited in the great Cretaceous inland sea.” (page 35).  We have trouble figuring out what happened at Mesa Verde in 1200.  Explain 78-91 million years ago to me.  For an obituary of Dr. Griffitts see https://www.dignitymemorial.com/obituaries/longmont-co/mary-oswald-griffitts-7928003
