The mountains above Idaho Springs and the nearby communities of Black Hawk, Central City and Georgetown show the abandoned mine openings and remnants of a romantic past: the "Rush to the Rockies" and feverish mining for silver and gold.

The Edgar mine, the Colorado School of Mines Experimental Mine, is a contemporary to that era. In the 1870s, it produced high-grade silver, gold, lead and copper. Today, as an underground laboratory for future engineers, it produces valuable experience for those who are being trained to find, develop, and process the world's natural resources.

As a subsidiary of Freeport-McMoRan, Henderson is the largest primary producer of molybdenum in the world. The Henderson Mine is located in Clear Creek County on the east side of the Continental Divide, in the beautiful Rocky Mountains fifty miles west of Denver, Colorado.

The Henderson Mill is located on the west side of the Continental Divide, fifteen miles from the mine in Grand County. The Mine and the Mill are connected by the world's longest conveyor of its kind; a fifteen-mile elevated belt that passes underneath the Continental Divide through an old train tunnel and then above ground to the Mill.

In operation since 1976, Henderson has produced more than 160 million tons of ore and 770 million pounds of molybdenum during the past 27 years.

The Henderson Operation has been ISO certified since 1992 and the current certification is ISO 9001:2000. In 1999, the company received an Environmental Awareness Award from the United States Forest Service for the design, engineering, construction and implementation of the 15-mile overland conveyor system.

In 2005 Henderson Operation received the environmental certification ISO 14001:2004. Henderson Operations received OHSAS 18001 certification in 2007. More information about the Henderson Mine is available at http://www.climaxmolybdenum.com/operations/henderson.htm

The Eisenhower/Johnson Memorial Tunnel is located in the Colorado Department of Transportation's Region 1, in Maintenance Section 9, and facilitates movement of people, and goods from the Eastern Slope of the Rocky Mountains to the Western Slope.

The Eisenhower/Johnson Memorial Tunnels are located approximately sixty miles west of Denver, Colorado on Interstate 70, and are a part of the Colorado Department of Transportation. We are one of nine Maintenance and Operations Sections dedicated to developing and maintaining the best possible multi modal transportation system for Colorado that most effectively moves people, goods and information.

The Eisenhower Tunnel Turns 40

March 8, 2013, marked the 40th anniversary of the dedication and opening of the westbound bore or the Eisenhower Tunnel at the Eisenhower/Johnson Memorial Tunnel west of Denver, which is the highest vehicle tunnel in the world at 11,155 feet. The Eisenhower Tunnel was the first of two bores to open to help facilitate easier transportation between Colorado's east and west slopes.

Each tunnel is equipped with a full transverse ventilation system that uses 14 centrifugal fans, each running 600 hp. More information about the Eisenhower/Johnson Memorial Tunnel is available at https://www.codot.gov/travel/eisenhower-tunnel
