Pipestone Tunnel

Pipestone Pass is located at the top of the Continental Divide. The Milwaukee Road known as the CMSTP&P wound there way from the water grade of the Jefferson River to crossing the Continental Divide south of Butte, Montana. Many of the tunnels did not require a complete tunnel lining but this one did. It also had the fancier columns with capitals, as well as the top cromn. I include two ends as that is what was used by the Milwaukee Railroad.
