Gilman is a former town located in southeastern Eagle County, Colorado in the United States. Founded in 1886 during the Colorado Silver Boom, the town later became a center of lead and zinc mining in Colorado, centered around the now-flooded Eagle Mine. It was abandoned in 1984 by order of the Environmental Protection Agency [1] because of toxic pollutants, including contamination of the ground water, as well as unprofitability of the mines. It is currently a ghost town on private property and is strictly off limits to the public. At the time of the abandonment, the mining operations were owned by Viacom International.
[edit] Description
The town sits at an elevation of 9000 ft (2,700 m) on a dramatic 600 foot (180 m) cliff above the Eagle River on the flank of Battle Mountain. It is located southeast of Minturn and north of Tennessee Pass along U.S. Highway 24. The remnants of the townsite are visible in many places along the curves of the highway. More recent housing situated on the steep flank of the mountain itself near the former mines.
The mining district became the richest and most successful in Eagle County over time. The mineral deposits are in sulphide ores, lying in irregular tongue-like lodes within layers of Leadville Dolomite (limestone). Some of these deposits were 200 feet by 150 feet thick and 400 feet long, transected by vertical ore "pipes"? cutting across rock layers.
[edit] History
The town and initial mining operations in the 1880s were developed by John Clinton, a prospector, judge, and speculator from nearby Redclliff. Several mining operations had sprouted along Battle Mountain by 1879, the first year of the Silver Boom. In 1887, gold and silver were discovered in two vertical chimneys at the Ground Hog Mine, which continued to produced gold and silver ore until the 1920s.
In the 1880s, Clinton acquired a number of mining operations in the vicinity, including the profitable Iron Mask, noted for its numerous caverns with crystal formations. Clinton developed the area as a town and improved the mining operations with higher capitalization. The town, which Clinton developed in order to keep miners at the site, was initially named for him. He donated the land for its initial schoolhouse and built its first boarding house. The Denver and Rio Grande Railroad reached the mining camp of Belden at the base of the cliff in 1882. By 1899, it had a population of approximately 300, as well as a newspaper, called the Gilman Enterprise.
In the 20th century, the mining operations transitioned increasingly to zinc, although the Eagle Mine was still the leading producer of silver in the state in 1930. Throughout most of the 20th century, the town and mining operations were owned by the New Jersey Zinc Company. The town population reached a peak of 8,970 in the 1960. At one time, the town had an infirmary, grocery store, and bowling alley. The town experienced labor strife several time in the 1950s, partly inflamed by the out-of-state corporate ownership. By 1970, total production at the mines was 10 million tons of ore; 393,000 troy ounces (12,200 kg) of gold; 66,000,000 troy ounces (2,100,000 kg) of silver; 105,000 tons of copper; 148,000 tons of lead; and 858,000 tons of zinc [2].
After the closure of the mine and the abandonment of the town, a 235-acre area, which included 8 million tons of mine waste, were designated a Superfund site by the EPA and placed on the National Priorities List in 1986. According to the EPA, the mining operations left large amounts of arsenic, cadmium, copper, lead, and zinc in the soil, and led to large fish kills in the Eagle River and threatened drinking water in the town of Minturn downstream on the Eagle River. The clean-up plan, implemented beginning in 1988 included plugging and flooding the Eagle Mine, collecting and treating mine and ground water in a new treatment plant, as well as removing, treating and capping the mine waste products. A report by the EPA in 2000 concluded that clean-up operations had substantially reduced public health risks and improved the water quality in the Eagle River. The State of Colorado also has pursued separate parallel efforts at cleanup and has reached agreements with Viacom regarding treatment of the site.
