A sunny early spring day at Chautaugua Park in Boulder, I got the flatirons - but missed the hundreds of
people where were hiking the trails, playing frisbee and just enjoying open space. The flatirons on accessible via trailheads in the Park, providing varied and
unique climbing routes, from technical climbs to easy grades.
The Flatirons were named by pioneer women after the flat, metal irons they used to press clothes. They consist of conglomerate sandstone that geologists estimate
to be 290 to 296 million years old. They were lifted and tilted into their present orientation between 35 and 80 million years ago.
