The Patten Creek Site (48PL68) is a prehistoric lithic procurement and workshop area located in the Hartville Uplift area north of Guernsey, Wyoming.. The predominant materials are Hartville (''Spanish Diggings'') Chert and small quantities of Hartville Quartzite. The site is a multiple component site with buried materials at least as deep as 3.6 meters. Early work indicates that Plains Archaic components are the most abundantly represented in the central portion of the site, but other components have been recorded as well. The site was first formally reported by the Smithsonian River Basin Survey for Glendo Reservoir as 48PL32, and later investigated more extensively in loose association with the Hell Gap Project of Harvard University. Excavations at the site were begun by Irwin and Irwin-Williams in 1960, and by Keller from 1963 through 1965. A minor Late Prehistoric component was recovered at Patten Creek, and it was speculated that quality lithic sources may have been locally exhausted by that time. Three distinct Plains Archaic components were identified which correspond roughly to the Early, Middle and Late Archaic. A single Frederick point was reported from the site, but the presence or absence of buried Paleoindian components at Patten Creek has not been demonstrated.

The Sunrise Mine Historic District encompasses 225 acres in the rural, high desert foothills of eastern Wyoming, where the Sunrise Iron Ore Mine and company town operated from 1898 to 1980. The now abandoned town of Sunrise, Wyoming, where the mining operations and company town were located, lies on the floor of Eureka Canyon, surrounded by canyon walls on the north, south, and east. The soil in the district is red, due to the large amount of red ochre that accompanies the iron and copper deposits scattered throughout the area.

The property contains buildings, foundations and landscape features representing 80 years of iron-ore mining, with an associated company town. The district is a part of the Hartville Uplift, an area in southeastern Wyoming that connects the southern Black Hills with the Laramie Range. The Sunrise Mine was the principal source of iron used at the Colorado Fuel and Iron plant in Pueblo, Colorado, from 1899 until 1980, making it an important contributor to the economy of Colorado as well as Wyoming. Also, the Sunrise Mine was important in the social and ethnic history of the region. The unskilled workers at Sunrise included Italians, Greeks, Syrio-Lebanese, Japanese, Scandinavians, and English.
