The Pierre Shale formation was deposited during the Paleogene and Cretaceous periods about 70 million years ago. The region was covered by a deep sea—the Cretaceous Western Interior Seaway—which deposited massive amounts of shale on the seabed. Both the thick stratum of shale and embedded marine life fossils—including ammonites and skeletons of fish and such marine reptiles as mosasaurs, plesiosaurs, and extinct species of sea turtles, along with rare dinosaur and bird remains—were created during this time period. The area now known as Colorado was eventually transformed from being at the bottom of an ocean to dry land again, giving yield to another fossiliferous rock layer known as the Denver Formation.[58]

Update on Jan. 14, 2019: A Rocky Mountain National Park spokesman said Monday the park began using recreation fees to temporarily pay about 10 percent of furloughed workers to clean up the park. They’ve been plowing roads, cleaning restrooms and collecting trash since Saturday. Other staff, such as law enforcement rangers, continue to work without pay during the shutdown. The park is expected to reopen to vehicle traffic on Tuesday, said Kyle Patterson, a Park spokesman who is on furlough.
