The Sunrise Iron Ore Mine is situated in Eureka Canyon in Platte County, Wyoming. The district is divided into three distinguishable sections: the railroad and maintenance yard, the mining zone, and the company town. Canyon walls define the 225.24 acre site on the north, south, and east. The property includes 35 buildings, sites and structures of historic significance to industry, engineering, community development, commerce, ethnic heritage (Asian and European), and social history. The site, as the key source of iron for the Colorado Fuel and Iron Company for eighty years, holds a significant place in the economic histories of both Wyoming and Colorado. Furthermore, the vast ethnic diversity among unskilled workers at Sunrise carries great importance for the social and ethnic history of the region.
