The Locus 7 Site is an archaeological site in Washington Township, Fayette County, Pennsylvania, United States. Located north of Fayette City, the site lies on a bluff over Downers Run[a] about 2,000 feet (610 m) from the Monongahela River.[b] It is believed to be the location of a former Monongahela village, but its date is uncertain; the village may have existed at any time between 900 and 1600.[2]: 2 Its location on a bluff is unusual for Monongahela village sites, but this may have contributed to its preservation; most riverside Monongahela sites in the valley of the Monongahela River have been destroyed by development.[2]: 3
Small-scale archaeological investigation at the site has revealed a wide range of pottery at the site, along with a significant amount of mussel shells; it is believed that a more extensive excavation would yield evidence of small round houses and a stockade.[2]: 2 Such a large amount of potential findings has been theorized because of the limited disturbance that the site has seen: unlike most Monongahela sites in the region, it has been damaged only by surface cultivation by local farmers who used only horse-powered equipment.[2]: 3
^a: While the source for this statement gives the name as "Douners Run," the United States Geological Survey has recorded the stream's name as given in the text.[3] ^b: While the source for this statement states that the site lies west of the river, this is impossible, as the land west of the river is part of Washington County.[4]
