Hygiene Sandstone, Boulder, Colorado

This day trip will visit outcrops of the late Cretaceous Hygiene Sandstone in Boulder County. The Hygiene Sandstone is approximately equivalent to the Shannon Sandstone of the Powder River Basin, and is commonly referred to as Shannon Sandstone in subsurface of the DJ Basin. Historically interpreted as deposits of “offshore bars”, the Hygiene Sandstone is currently interpreted as the easternmost deposits of the Iles Formation (Mesaverde Group) deltaic complex of northwestern Colorado. The apparently isolated sandstone bodies are explained as remnants of deltas deposited during the falling stage or lowstand of a forced regression. Sediment textural and compositional properties, sedimentary structures, and depositional architecture will be analyzed to lead into a discussion of the dominance of tidal processes, deltaic nature and the paleogeographic position of the Hygiene Sandstone. Sedimentary characteristics observed in outcrop will be compared with a core from the DJ Basin.
