Map showing outstanding natural and historic landmarks in the greater Denver area, Front Range Urban Corridor, Colorado

The preservation and protection of landmarks of outstanding natural and historical significance has become a matter of increasing public concern as man's ability to alter the landscape has increased.  Congress expressed its concern in 1969 in its passage of the National Environmental Policy Act.  The purpose of this report is to identify and inventory such landmarks.  Appropriate consideration in land-use planning and development can then follow.
