[Linked Image from hosting.photobucket.com]The Carlton Drainage Tunnel (also an adit), was also constructed to drain the same mining district as the mines went deeper than the Roosevelt Drainage Adit. The project was began in 1939 and also went through solid granite. The adit portal is at about 7,000 feet elevation, and the adit itself is over 6 miles long. It’s about 2.5 to 3 miles further down in the same canyon that the Roosevelt adit portal is in. It allowed the bigger mines in the area to go even deeper. It is still draining water from the area to this day, at the rate of about 1,600 gallons per minute. The flow goes right into Four Mile Creek and then flows into the Arkansas River at Cañon City.

Every day on this side of the ground is a win.
