3D model of two parasequences of a clastic, shallow marine outcrop in the Western Interior Basin (Judith River Formation, Cretaceous)

Two 3-dimensional models from the Parkman sandstone, at the base of the Judith River Formation (Cretaceous). The study area is located west of the town of Bridger (Montana, USA). These models were acquired for the analysis of lateral and vertical stratigraphic heterogeneities in clastic, shallow marine environments. The models cover a cliff section of, approximately, 1500 m in the horizontal direction and 150 m in the vertical direction.

The resolution of the models, measured in GSD (ground sample distance), varies between 0.03 and 0.04 m.
