The East Portal Camp Cabins, built at the east entrance to the Moffat Tunnel in Gilpin County, remain the last remnants of a “factory system” town for workers who bored through the mountain to accomplish one of the most important engineering accomplishments in U.S. history.  Although not the first to conceive of a tunnel under the Continental Divide, David H. Moffat’s determination to unite Denver with the West Coast by railroad was the guiding impulse that led to the building of the Moffat Tunnel.  Once completed, the Moffat Tunnel eliminated 150 miles off of the transcontinental routes, allowing trains to pass through the divide with ease. 

The construction camps at the East Portal (Gilpin County side) were built in 1922-23 prior to the commencement of work on the tunnel itself.  During the late 1920s, most large-scale engineering projects were plagued with high labor turnover, low morale, dangerous working conditions, and a general unwillingness to stay.  Contractors Hitchcock and Tinkler determined that the best way to achieve better results and a good work ethic was through a well designed, built environment that would include comfortable accommodations, efficient workspaces, social activities, and a readily available food supply.  Tinkler and Betts hired Colorado engineer Clifford A. Betts, who organized the company town on either side of an east-to-west bearing main street projecting from the tunnel outlet.  Along the main street, the utilitarian shops were located closest to the tunnel; the bunkhouses and recreation facilities were located just west of the shops; and the entire entity was enclosed with a fence.  East of the bunkhouse and shop complex was the “Cottage Village,” which was originally a complex of eleven single family cottages arranged north of a street.  The cottages employed features evocative of fashionable early twentieth century residences, with wide eaves, low gable roofs, and exposed rafters. 

The five surviving East Portal Camp Cabins provide the only remaining built connection with the individuals that built the tunnel, including 28 workers who died in the process.  The cabins are located at the base of the James Peak Trail leading into the James Peak Wilderness area, which provides easy access and the opportunity to introduce this important history to thousands of trail users.  The buildings sit on U.S Forest Service land but are owned by Union Pacific’s Real Estate Department. CPI held an initial site orientation meeting with the Gilpin County Historical Commission and other partners. The GCHC and Union Pacific are in negotiations about acquiring the cabins, but an environmental and structural assessment must be done. Rehabilitation of the cabins could provide adaptive re-use options that would benefit several potential partners while saving this important remnant of one of the most important achievements in American engineering history.

Weather continues to take a toll on the cabins near Rollins Pass

Preservation for a Changing Colorado

Historic preservation has a direct economic benefit to communities and Colorado! Take a look at the 2017 study, which considered the ways adaption of historic places has a direct financial effect on the state.

This updated, most resent study, was the result of a partnership between Colorado Preservation, Inc and History Colorado, funded by a grant from History Colorado's State Historical Fund. Prepared by Clarion Associates, the new report document the economic benefits of rehabilitation projects, analyzes property values and neighborhood stability in local historic districts, and summarizes the increasing impact of heritage tourism, private preservation development and the success of Colorado’s Main Street program.

In a key finding, researchers determined that for every $1 million spent on historic preservation in Colorado it produced $1.03 million in additional spending, 14 new jobs, and $636,700 in increased household incomes across the state!

The 2017 report also considers the important role preservation plays in helping Coloradans provide new spaces for creative communities and co-working, create and sustain meaningful places, responds to the state’s changing demographics, and addresses climate concerns.
