The Colewood Tunnel is in City of Creede, Colorado. Historically the site has been associated with the Creed Mining District which is now part of the Rio Grande National Forest.

The ore body extends 0.30 meters (0.98 feet) in width. Associated rock in this area is rhyolite from the Oligocene epoch 33.90 to 23.03 million years ago. The Southern Rocky Mountains physiographic province of the Rocky Mountain System characterize the geomorphology of the surrounding area.

1 World-class significance is determined by total endowment of the contained commodity. This includes all past production and remaining reserves. Each commodity is considered separately and commodities cannot be combined to arrive at a significant size. The tonnage thresholds are from the mine model grade-tonnage studies. As of June 2008, many entries were classified as significant under less strict rules.
