The Colorado Province took shape as a mobile belt—an area of thinner, orogeny related continental crust lacking the deep "keel" of rock, which stabilized the neighboring Wyoming Craton and other cratons like it. Throughout Colorado's geologic history, rocks have often been deformed, metamorphosed and overprinted, obscuring the ancient record.
The rocky cores of the mountain ranges are, in most places, formed of pieces of continental crust that are over one billion years old. In the south, an older mountain range was formed 300 million years ago, then eroded away. The rocks of that older range were reformed into the Rocky Mountains. The Rocky Mountains took shape during an intense ...
Rocky Mountain National Park is a national park of the United States located approximately 55 mi (89 km) northwest of Denver [5] in north-central Colorado, within the Front Range of the Rocky Mountains.

The Denver Basin, variously referred to as the Julesburg Basin, Denver-Julesburg Basin (after Julesburg, Colorado), or the D-J Basin, is a geologic structural basin centered in eastern Colorado in the United States, but extending into southeast Wyoming, western Nebraska, and western Kansas. It underlies the Denver-Aurora Metropolitan Area on ...
The Flatirons are rock formations in the western United States, near Boulder, Colorado, consisting of flatirons.There are five large, numbered Flatirons ranging from north to south (First through Fifth, respectively) along the east slope of Green Mountain (elev. 8,148 ft or 2,484 m), and the term "The Flatirons" sometimes refers to these five alone.
The Colorado Plateau is a physiographic and desert region of the Intermontane Plateaus, roughly centered on the Four Corners region of the southwestern United States. This plateau covers an area of 336,700 km 2 (130,000 mi 2) within western Colorado, northwestern New Mexico, southern and eastern Utah, northern Arizona, and a tiny fraction in ...
Fountain Creek. Named by. C. W. Cross, 1894. The Fountain Formation is a Pennsylvanian bedrock unit consisting primarily of conglomerate, sandstone, or arkose, in the states of Colorado and Wyoming in the United States, along the east side of the Front Range of the Rocky Mountains, and along the west edge of the Denver Basin.
The Rocky Mountains, also known as the Rockies, are a major mountain range and the largest mountain system in North America. The Rocky Mountains stretch 3,000 miles (4,800 kilometers) [3] in straight-line distance from the northernmost part of western Canada, to New Mexico in the southwestern United States. Depending on differing definitions ...
