Denver Formation, Geological formation in Denver Basin, Colorado
The Denver Formation is a geological sequence of sandstone and shale layers that extends beneath the central Denver Basin. These rocks formed in an ancient sea and reveal different sediment deposits from that distant period.
The formation developed 68 to 80 million years ago when a vast sea covered what is now Colorado. After the sea retreated, the layers remained and continue to shape the region's geology today.
Research teams conduct regular field studies at the formation sites, examining sedimentary structures and collecting fossil specimens for scientific documentation.
Exposed rock layers can be viewed at several locations such as Green Mountain, where trails make different levels of the formation accessible. The best time to explore is during warmer months when conditions are most pleasant.
Dinosaur remains such as Triceratops bones and Iguanodon tracks can be found at certain locations, offering glimpses into prehistoric life. These fossils make the formation a valuable window into Colorado's past.
