Another shot from the archives. D&RGW #478 makes its way through the Animas River Canyon at a location known as Cement Wall. The narrow sliver of land that the tracks occupy and their position on the outside of a bend in the river made them a constant problem due to washouts. In response, the railroad poured a large cement wall to protect the tracks, giving this location its name.
This was taken on a private photo charter on the Durango & Silverton back in February 2011. Hard to believe this was 7 years ago as well.
