Particularly rich is the collection of earthenware from the site, which is so comprehensive as to make it a potential type site for the culture's pottery. As a well-preserved Allison-Lamotte village, Stoner is unusually valuable: it retains substantial evidence of that culture's occupation, and this evidence is unmixed with materials from other cultures. As a result, the Illinois Archaeological Survey deemed it the state's purest example of the culture, and two of its archaeologists predicted that future excavations would be able to gain crucial evidence of daily life from its richness and purity. Into the late 1970s, the distinctions between Allison-Lamotte and contemporary cultures elsewhere in the region were poorly known, so the IAS archaeologists suggested that excavations at Stoner would permit researchers to draw much clearer conclusions about the relationships between the different cultures living along the Middle Wabash in the Middle Woodland period. In 1978, the Stoner Site was listed on the National Register of Historic Places because of its archaeological potential. It is one of three archaeological sites in Crawford County to be accorded this distinction, along with the Riverton Site (type site for the Riverton culture) and the Riverton-era clam shell midden known as the Swan Island Site.
