National Landmarks in Jeffco

As of August 2015, the National Park Service has designated a new National Landmark in Jefferson County, bringing our total to two illustrious, nationally recognized sites.

workerRed Rocks Park and
Mount Morrison Civilian Conservation Corps Camp
National Historic Landmark, August 4, 2015

Secretary of Interior Sally Jewell signed this designation, bringing a decade-long process to a close. The park represents a rare and outstanding example of New Deal work in collaboration with local government to develop public landscapes and outdoor recreation.

We anticipate this will be celebrated with a plaque and dedication in 2016, in conjunction with the 75th anniversary of the completion of Red Rocks Amphitheatre.

What are National Landmarks?

National Landmarks are a much more prestigious and exclusive designation and the nomination process is more detailed. The landmarked properties must have national significance beyond their basic historical or natural values.

In contrast, National Register listing is a process for recognizing sites that are usually at least 50 years old, and are significant according to listing criteria, including things like their association with historic people, events, etc. Colorado has more than 1400 sites, buildings, and districts listed on the National Register, but only 25 National Historic Landmarks and 14 National Natural Landmarks.

Although none of these designations confer protection on a property, the landmarks do involve some federal review to ensure the landmarked sites maintain the qualities that make them significant and worthy of this high honor. (See Withdrawal of Designation at
