History
Eagle County was created by the Colorado legislature on February 11, 1883, from portions of Summit County. It was named after the Eagle River, which runs through the county. The county seat was originally set in Red Cliff, Colorado, but was moved to the town of Eagle in 1921.
The Ground Hog Mine, near Red Cliff, produced gold and silver in two vertical veins in 1887. One vein, or "chimney", contained gold in crystalline form, cemented by iron, while the other contained wire gold in the form of "ram's horns".
