The Flatirons, Boulder, Colorado
The Flatirons. This formation was caused by the actions of a Rayleigh Wave emanating from a meteor impact centered 85 miles to the East. This action is similar to the formation of the Rock of Gibraltar at the western edge of the Mediterranean Sea.

The Flatirons Meteor Impact was centered at  40° 3'6.95"N 103°47'9.53"W. The 80 mile radius seismic circle of the impact formed the circular arc of the Front Range in Colorado.
      The Flatirons Meteor Impact was centered at   40° 0'37.50"N  103°40'57.34"W. The 85 mile radius seismic circle of the impact formed the circular arc of the Front Range in Colorado.
