This photo is from a collection of glass negatives I have. It was taken in Colorado, somewhere in the Boreas Pass or Como area I believe. A very well dressed lineman making some sort of repair to the lines. The insulator to his right looks to be a CD 145 beehive. Notice the narrow guage tracks. Probably either the Colorado and Southern or the Denver, Leadville and Gunnison railroad. Dates to around the 1901-1905 period.
