|Monongahela, Youghiogheny and lower Allegheny valleys|
Archaeologists began exploring prehistoric Native American sites in the Monongahela, Youghiogheny and lower Allegheny valleys as early as the late 1800’s when much of the emphasis was placed on mounds (cf. Hayden 1883; Thomas 1894; Carpenter 1951). Other sites were added by the Pennsylvania Indian Survey in 1928 under the direction of Dorothy Skinner. This was an expansion of the work begun in 1924 by Frances Dorrance, Director of the Wyoming Historical and Geological Society (Smith and Herbstritt 1977).
In addition to the interest in mound sites other information was published in the 1930”s (Cadzow 1933); Engberg (1931); George Fisher (1930) that broadened the distribution of sites known at that time for southwestern Pennsylvania, especially Late Prehistoric villages located in upland (hilltops and mountain ridges) and valley settings.
Archaeological investigations in Somerset County during the late 1930’s identified a number of Native American villages. The work was done with government funding through the Works Progress Administration better known as the WPA. In a report to the Pennsylvania Historical Commission, Dr. Mary Butler (1939) linked these people to a mixed material culture having Algonquin and Iroquoian traits and so named it the “Monongahela Woodland Culture”.
Over time, archaeologists dropped “Woodland” from the name, and the “Monongahela Culture” was borne into the literature that presently describes the Late Prehistoric through Protohistoric period Native American occupations of southwestern Pennsylvania where their material traits are found (Mayer-Oakes 1955).
The Carnegie Museum carried on its research interest into Monongahela archaeology after Mayer-Oakes field work was completed and published in the museum’s Anthropological Series No. 2 “Prehistory of the Upper Ohio Valley: An Introductory Archaeological Study” (Mayer-Oakes 1955). Don Dragoo (1955) and later, Richard George (see for example 1974; 1978; 1983; 2011) who conducted field work and published extensively on the Monongahela Culture, began organizing the differences observed in the artifact assemblages using the concept of “Phase” developed by Gordon Willey and Philip Phillips (1958) which with some modification remains in current use (Herbstritt 2003; Johnson and Means 2020). The following cultural phases/subtraditions for Monongahela are in current use.
Early Monongahela 1050-1250 AD Drew, Kiskiminetas,
Somerset I subtradition
Early Middle Monongahela 1250-1450 AD Campbell Farm,
Somerset II subtradition
Late Middle Monongahela 1450-1580 AD Scarem, Youghiogheny, Johnston,
Terminal Somerset II subtradition
Protohistoric Monongahela 1580-1640 AD Throckmorton (Early sub-phase), Foley Farm (Late sub-phase)

Attempts have been made to link the cultural identity of Monongahela to different Native American language groups such as Siouan and Iroquoian based on linguistic (cf. George 1980, Johnson 2001; Sorg 2003; Swauger 1974), oral history and the cartographic/historical record (Hoffman 1964), research topics that have drawn critical review.

Archaeologists recognize the disappearance of the Monongahela culture from the archaeological record in the mid-1600’s. The impact of European diseases is not certain. Iroquois warfare is more easily supported. Droughts played a significant role in reducing the population of Monongahela villages and impacted survival. Examination of the curated artifacts and site information for these villages, as well as more recent excavations has enabled archaeologists to gain a better understanding of this culture group.

To learn more about the Monongahela Culture please join us in Harrisburg on November 9th 2019 when the State Museum of Pennsylvania will host its annual Workshops in Archaeology Program “Defining Monongahela: Western Pennsylvania’s Archaeological Mystery”. This is a program for the general public interested in how Native Americans lived in the Upper Ohio Valley centuries ago. Featured will be different topics on Monongahela Culture with eight presentations by archaeologists familiar with this unique Native American culture that disappeared in the early 17th century.
