Flatirons, Boulder, Colorado - 4" x 4" Sandstone Coaster

The titled “Flatiron” sandstone slabs of the Fountain Formation provide an infamous backdrop for Boulder, Colorado. Whether you are a CU Buff from the University of Colorado, a hiker, a mountain biker, or technical climber, you’ll love the view captured in our 4.25″ x 4.25″ ceramic coaster.
