The West Elk Mine, owned by Arch Coal Inc., and operated by Mountain Coal Company, is a 7 million tons-per-year coal mine utilizing state of the art mining techniques. The mine is located on the Western Slope of Colorado 12 miles east of Paonia on Hwy 133.

The West Elk Mine has been developed in the coal seams of Cretaceous Mesaverde Formation in the far southeastern tip of the Piceance Basin. Numerous structural and geologic features have been encountered within the mine including sedimentary dikes, rock partings, compactional faults, and tectonic faults. The mine tour will examine the geology of the mine, visit continuous-miner development and long-wall mining sections, and review the degasification and exploration activities associated with coal mining.

Directions: from Grand Junction travel 30 miles south on Hwy 50 to Delta. Turn east on Hwy 133/92 towards Paonia approximately 31 miles from Delta. At Hotchkiss Hwy 92 splits to the south; remain on Hwy 133. The group may overnight in Paonia or Hotchkiss. There is a back way from Glenwood Springs on Hwy 133 through Carbondale, Redstone, and over McClure Pass. A good trip in July!

Place and Time: We meet at the Breakfast Shop nevi to the Redwood Arms in Paonia on Saturday at 6:30 am. We will caravan to the mine from the restaurant. Participants are responsible for their own motel reservations. There is a list of motels and phone numbers below.
