Rock Formations to Explore in Boulder County
FlatironsOne of the most spectacular city views in the country. The dramatic rock outcroppings as well as the hiking trails will afford life-long memories. 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. They are popular destinations for hikers and rock climbers, with rock grades ranging from easy to world-class.
