A new view on Rock Tunnel, showing it in the context of the rugged and massive Toltec Gorge. In the far upper left you can make out the line miles back toward Antonito, and even further the distant Sangre de Cristo Mountains. Below, DRGW 168 pulls a mixed train along the edge of the gorge toward Osier amid peak fall foliage. This was from a Dak Dillon photo charter.
