COLORADO MAGAZINE Published Bi-Monthly by the State Historical Society of Colorado
THE COLORADO MAGAZINE Published bi-monthly by The State Historical Society of Colorado Vol. XV Denver, Colo., May, 1938 No. 3 Was "Mountain District No. I , Nebraska Territory," the First Mining District Organized in Colorado? PERCY S. Jl"'RITz• January, 1859 ! A typical Colorado January it was. Nothing remarkable or unusual to the Indians who followed the elk down from their mountain fastnesses to the foothills. Most of the days were clear and comfortable, even outdoors, with the bright Colo rado sunshine. Snow had fallen early the preceding fall. On the last day of October a ten inch blanket of snow chilled the enthusi asm of the band of about one hundred gold seekers huddled about the mouth of Cherry Creek. To them a town-site became more important than gold and Auraria was born that very night. But by January they were not as badly snowed in as they had feared. The foot-hills were covered with snow which, in the shady spots in the gulches and where it had drifted, was sometimes three feet deep. Although the sunshine was still warm, the nights were severely cold. The ground was "hard frozen'' and Clear Creek, as one looked down upon it from Lookout Mountain, was frozen solid.1 January, 1859, was not remarkable on accolmt of its weather, but it was made historic by a remarkable series of gold discoveries. During this month gold "·as discovered at the sites of Idaho Springs, Black Hawk, Gold Hill and Deadwood Diggings. On January 7, 1859, George A. Jackson after thawing the ground by keeping up a large fire, found gold on the little creek, now called Chicago Creek, entering Clear Creek at Idaho Springs.2 On Janu ary 16, 1859, a party of six men from the camp at the mouth of Boulder Canyon struck gold at the foot of Gold Hill. -

Rush to the Rockies, 1859
82 COLOHADO MAGAZINE 83 Rush to the Rockies, 1859 Colorado's Gold Rush of 1859 By AGNES WRIGHT SPRING "It was an uncontrollable eruption-a great river of human life rollin* toward the setting sun-at once a triumph and a prophecy. A. D. Richardson in Beyond the Mississippi. "THE NEW ELDORADO!!! Gold in Kansas Territory!! The Pike's Peak Mines! First Arrival of Gold Dust at Kansas City!!!" These were the headlines in the Kansas City Journal of Commerce of August 26, 1858. The words spread like sparks from a roaring prairie fire before a strong wind. They were the words men all over the depression-ridden country had been hoping for. Not only word of the discovery of yellow metal, but several ounces of the precious gold itself had been brought to Kansas City by well-known mountain men. "\Ve have refrained from giving too much credence to these gold discoveries until assured of their truth,'' said the Editor of the Journal, "but it would be unjust to the country longer to withhold the facts of which there can no longer be a doubt. Kansas City is alive with excitement, and parties are already preparing for the diggings." The new mines, it was explained, were on Cherry Creek, one of the "most southern branches of the South Platte, in the center of the best hunting grounds of the Rocky Mountains. Game exists in great abundance, and plenty of timber, water and grass." John Cantrell, one of the gold-bearing arrivals from the mountains, was no stranger in Kansas City. -
Phase I Environmental Site Assessment Schoolfield Placer and Third National Mill Site, Stanley Road, Dumont, Colorado
Phase I Environmental Site Assessment Schoolfield Placer and Third National Mill Site Dumont, Colorado 80436 June 5, 2019 Prepared By: Sundance Environmental Consultants, Inc. 11584 Wilson Circle, Parker, Colorado 80134 (303) 699-7870 Prepared For: Jason Smith Phase I Environmental Site Assessment Schoolfield Placer and Third National Mill Site, Stanley Road, Dumont, Colorado 1 SUMMARY The subject property consists of approximately 11 acres of land associated with historic mining claims, including hard rock mining, placer mining, and potentially milling operations. A railroad was historically present along the northern edge of the site. Most of the mining activities occurred in the late 1800s and early 1900s, although one mine area may still be in use. Several mine rock piles are visible on the subject property, and the toe of a mine rock pile that is still in use encroaches onto the Third National mill site portion of subject property. This pile displays rock fragments that are yellow or golden in color, and is not vegetated. The bulk of the property contains grasses and trees on mountainous land that steepens uphill toward the south. Several debris piles were noted on the subject property, mostly consisting of dead wood. Some rusty metal pipe and rusty wire rope were observed in one pile. Some limited building material such as wooden lattice had been dumped. Trash on the ground included metal cans, plastic bottles, empty burlap sacks, shot gun shell casings, old rubber hose, and a small piece of linoleum. No chemical containers or ground staining were observed on the subject property. This debris did not appear to contain any significant evidence of hazardous substances or petroleum products. -
