I have visited this site a few times, it is a fascinating place, but hard to reach. The plant was built in 1900 and ran until 1965. It produced 30 cycle AC and powered the Cripple Creek District, the trolleys in Pueblo, Pueblo itself and Canon City. The incline is quite a piece of engineering, four bridges and a tunnel, with the pipeline (penstock) under the track. The rail and the big bridge in the photo are gone, but the little incline car is still there. The plant is heavily vandilized, but is remarkably intact. The dam at Skaguay Reservoir (yes spelled with a "u" not a "W") is the worlds first steel faced, rock filled dam. It was built by blasting the top off of a nearby hill and hauling the rocks down on a three foot gauge, two car incline railway, using D&RG flatcars, which I believe were borrowed for the project and later returned. I have yet to make out the car's numbers in the old photos.
Other than railroads my passion is old power plants, particularly hydro's. I am collecting as much information I can on all of the plants that are or were in Colorado for a book I am writing. If anyone has any photos or infomation, or would like more information on Skaguay I would love to speak to you.
