The Boulder Flatirons
The mountains directly above Boulder are one of the best parts about living here. The major areas are from south to north (left to right) Eldorado Canyon, The Flatirons, Flagstaff Mt and Boulder Canyon. The Flatirons are the region between Shadow canyon and Gregory Canyon (see map below).
