The Flatirons consist of conglomeratic sandstone of the Fountain Formation. Geologists estimate the age of these rocks as 290 to 296 million years; they were lifted and tilted into their present orientation between 35 and 80 million years ago, during the Laramide Orogeny. The Flatirons were subsequently exposed by erosion
