The Flatirons are a part of the Fountain Formation—a rock unit that stretches along the eastern margin of the modern-day Front Range.

What are the Flatirons made of?
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.
How were the Flatirons formed?
The Flatirons are part of a rock unit known as the Fountain Formation. These rocks are sedimentary—that is, rocks that have been formed by broken fragments of older rock. The Fountain Formation was deposited approximately 280 million years ago, during a time geologists refer to as the Pennsylvanian Period.
