Endangered Places

mepl logo no list or date

Since 1997, Colorado Preservation, Inc. has developed Colorado’s Most Endangered Places Program to build awareness of, and assistance for, historically significant places within the state that are in danger of being lost. The success of the Endangered Places Program is based on the dedicated efforts of concerned citizens, legislators, local governments, commercial businesses, organizations and foundations, members, and donors who have contributed to successful partnerships and preservation solutions.  The purpose of the program is to elevate the discussion and ramp up local action toward saving significant places that matter to Coloradans.  One myth is that the listing “Endangered” is a platform to cast shame on a property owner, organization, and/or community.  This is far from the case – the intent of the program is to demonstrate how important the site is and to serve as a collaborative catalyst for positive change.

Meaning Behind the Categories of  Save, In Progress, Alert, and Lost

These categories are often site specific as to what they actually constitute; however, generally a “Save” constitutes that the historic resource is no longer endangered and threatened. This often means that one or more of the following have been completed:  rehabilitation, restoration, preservation, conservation, documentation, stabilization, interpretation. When sites are ”In Progress” this means that they are currently in the process of the aforementioned; however, the work is not complete. “Alert” means that the Listed sites are still in the planning process to become a “Save,” and “Lost” means that the site has been demolished.

What We Have Learned…

Lost Since inception of the Endangered Places Program in 1997, Colorado Preservation, Inc. has only lost 6 sites. While this is a good track record, with these losses there are important lessons to be learned. One of the biggest lessons we have learned is that community support is huge. How a site moves from “Alert” to a “Save” depends in great part on how involved and dedicated the community is to protecting the resource. In recent years with the loss of the Given Institute in Aspen, and the Baldwin building in Holeyoke, we have learned that it is best to be pro-active regarding advocacy and outreach on the benefits of preservation and historic resources in general. Over the years we have also learned the importance of engaging, educating, and empowering communities not only with the outcome of a particular listed endangered resource, but also on how to prevent future threats.

4 Bar 4 Ranch

Homesteaded in 1895 by Dick McQueary to provide a stop for the Georgetown Stage Line, the 320-acre 4 Bar 4 Ranch has strong ties to Grand County and Colorado's heritage. The Georgetown Stage Line traveled on the road through the 4 Bar 4 Ranch from Idaho Springs to Hot Sulphur Springs over Berthoud Pass. In 1895 a roadhouse and stage stop were constructed on the ranch. The hotel and barn were constructed using trees from the Ranch property, and the hotel remained open for travelers coming over Berthoud Pass by horseback and wagon until 1913. With the coming of the automobile, the roadway over Berthoud Pass and through the 4 Bar 4 Ranch was considered an integral part of the Trans-Continental “Midland Trail” highway. Following the closing of the stage line, the ranch continued to host travelers until 1912 or 1913 when it was purchased and converted into a Ford Motor Company . Ford vehicles were sold here until 1917, when Harry Larkin purchased the ranch site. Today emergency efforts are underway to ensure it survives through the winter. Donations are in need.
