Squire and Davis first discovered and recognized items found in Ross County, Ohio, in 1846 as being different from Hopewell (see reference 1). William C. Mills of the Ohio Archaeological and Historical Society in the early 1920s is credited as being the first to use the term “intrusive.” His work in Ross County revealed numerous later cultural burials to be found near the tops in several Hopewell mounds. Later in the 1930s, William Ritchie, archaeologist for New York State, formally named the culture “Intrusive Mound” following his work in central New York State at several locations, including the Kipp Island Site (see reference 2). These later Woodland people sometimes buried their elite and high ranking noble in existing Hopewell and very occasionally in Adena Mounds, hence the name “intrusive” and “mound” came together. Almost all Intrusive Mound (IM) burials in Ohio are in Hopewell mounds. Several Intrusive sites outside of Ohio and especially to the east were discovered in earlier Adena conical mounds.

While there were several Late Woodland Period cultures in the eastern and central United States, arguably, the predominate one in Ohio and eastern Indiana was the Intrusive Mound people. Intrusive Mound sites have been reported, however, from New York and Ontario in the northeast, as far south as central Tennessee, and westward to Indiana and Michigan. The greatest concentration of sites lay in south-central Ohio with Ross County being the possible epicenter. Evidence of Intrusive Mound occupation (primarily arrowheads) has been recovered across the northeast, throughout the Great Lakes and as far south as Alabama.

Late Woodland villages were typically larger and more widely separated than those of earlier cultures. People inhabited these village sites for several years as opposed to one or two seasons before moving on. The communities relied more on domesticated agriculture as well as meat and fish for both short- and long-term survival. Crops grown were squash, gourds, may-grass and, in later years, beans and maize. By the end of the period, maize was widely grown and was a primary food source. Several professionally excavated Intrusive Mound villages have revealed stockade walls complete with large midden/dump sites. As towns contained more inhabitants than earlier Adena and Hopewell communities, it was natural their larger and longer occupations led to bigger communal middens. As the Late Woodland Period evolved, villages and communities continued to become larger, weapons became more accurate and widespread, and defensive mechanisms became prominent. The presence of stockade-like structures indicates a need for increased protection from outsiders, be they beast or human.

The Intrusive Mound Culture is defined primarily by goods recovered from graves and middens. Unfortunately, while few sites in number, there have been even fewer professionally excavated and well documented. Many Intrusive Mound pieces have little or no provenience but are characterized only by those few that have been excavated, catalogued and portrayed. Intrusive Mound artifacts recovered to date are fine flint as well as antler tine arrow points, flint spear points, chert celts and scrapers, shell beads, antler hair combs, bone harpoons, slate and hardstone pendants, steatite and chlorite smoking pipes, ceremonial picks, and several face masks. An excellent recent magazine article featuring Intrusive Mound picks was written by Dr. Sandy B. Carter, Jr. (see reference 3).

The Jack’s Reef type point was possibly the most widely distributed and used point of the time. These points are significant as they are some of the first true arrowheads. It is believed that bows and arrows were first introduced into the Midwest approximately AD 800, making the Intrusive Mound people some of the first to employ this tool/weapon. Several examples of these first true arrowhead points are shown in Figure 1.

One very interesting and rare artifact type of the Intrusive Mound Culture is ...
