The John Trezise Archive

At our book launch event held Saturday, May 12, 2018 for Rollins Pass: Images of America (2018) and Rollins Pass: Postcards of America (2018), we announced the creation of The John Trezise Archive for Rollins Pass Imagery.


This is the world’s largest collection of Rollins Pass imagery that is crowd-sourced, completely searchable and available to the public through partnerships with requesting museums/libraries, and secured from loss. (Please note, this is separate from our call for photos on this webpage.)

The John Trezise Archive for Rollins Pass Imagery has already provided multiple rare images of the 1913 D&SL 10300 steam crane to the Moffat Road Railroad Museum in Granby, Colorado, contributed to published works by other Colorado authors, among many other projects—all to inform the present understanding of Rollins Pass by leveraging information provided from high-resolution historical images of the past. If you’d like to make a contribution to this archive, please reach out and contact us.

“Many pictures are from the collection of John T. Trezise, a locomotive engineer whose collection of snapshots reveal the unseen Rollins Pass; John, may you rest in peace having found a form of immortality within these pages.”

—from the Acknowledgments, Rollins Pass (2018), by B. Travis Wright, MPS and Kate Wright, MBA with a foreword by Jason M. LaBelle, PhD


In recent years, as our work on the Moffat Tunnel and the East Portal Camp Cabins has gained momentum, we’ve assembled an incredible collection of rare Moffat Tunnel-related historic journals and imagery—some of which belonged to the now disbanded Moffat Tunnel Commission. This collection has also been folded into the John Trezise Archive.

The primary purpose of our work is to inform the public.
