Year round, adventure seekers head to Boulder, Colorado, a college town nestled at the base of the iconic Flatirons, slanted sandstone formations, to engage in a variety of outdoor activities. The name Flatirons dates to an earlier era when pioneer women compared these rocks to the metal irons they used to iron their clothing. Today, few are aware of this trivia. Instead, climbers arrive with a wide range of abilities to tackle this focal point of the Boulder County trail system.
