Archaeological\  investigations\  at\  the\  Mon\  City\  Site (36WH737) on the west bank of the Monongahela River in Washington County, Pennsylvania revealed portions of a Late Prehistoric Monongahela tradition small habitation site. This site occupied a narrow Holocene levee between the Monongahela River and a back channel slough. Evidence of one house pattern was documented as were storage facilities, pit features, and a hearth. Pottery attributes, including a high percentage of final Z-twist cordmarking and dowel impressed lips, exemplify the late Middle Monongahela period. Uncalibrated radiocarbon dates indicate mid-sixteenth-century occupations. Subsistence remains reflect the exploitation of a variety of wild resources available within the immediate vicinity of the site and nearby uplands in addition to maize-based agriculture. The Mon City Site and another recently reported small habitation site indicate that this relatively poorly known class of sites played important roles in Middle Monongahela subsistence-settlement systems.
