The original building covering the quarry wall was raised from 1957 to 1958. Over the years, Chure, park staff, and interns have been looking through historical documents to piece together the living history of the quarry. (Brian Switek)Bracing himself against the Jurassic sandstone, high above the floor of Dinosaur National Monument’s bone-packed quarry wall, paleontologist Dan Chure recalls some of the original plans for the ancient graveyard. The sandstone varies in hardness and composition throughout the quarry, Chure says, leading the more friable areas to crack and damage bone more easily. Geoscientist-In-Park Nicole Ridgewell is spending her entire summer picking over the quarry face, researching and documenting how to keep the Jurassic fossils together.
