Endangered Places Archives

In creating the Most Endangered Places list, Colorado Preservation, Inc. staff and a dedicated team of volunteers work over a period of several months to review, meet, and debate the merits and needs of each nominated site.  The goal is to find the places that best represent the two primary listing criteria; historic significance and the threat of being lost.  But more than just meeting the criteria, the review committees are seeking to find the places that matter; those that tell a story by servicing as the physical representation of some period in history.

Sites in blue have been saved.  Sites in red have been lost.

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.
