Here is another photo from my collection of glass negatives. This one is a lineman clinging to the side of a rocky gorge over the tracks. It is so cramped for space that there is not enough room for a pole! There is a crossarm anchored with some metal struts directly behind him. The insulators appear to be CD 145 beehives or possibly CD 162 signals. I wish I could see more of what is in his kit that is visible in the lower right hand corner. I believe this to also be in the Boreas Pass or Como area. The narrow guage railroad is probably the Colorado and Southern or the Denver, Leadville and Gunnison line. dates to the 1901-1905 period.
