The Vore site was discovered during the construction of Interstate Highway 90. Archaeologists from the University of Wyoming spent two summers in 1970 and 1971 determining the horizontal and vertical extent of the cultural materials, which measured nearly 150 feet wide by more than 20 feet deep. Analysis of these excavations established the Vore site as one of the most spectacular large mammal kill sites known in the world. It is also one of the most significant Plains Indian sites for the critical Late Prehistoric Period it represents. Additional excavation has occurred since the mid-1990s, and with less than 10 percent of the site excavated, its research potential for understanding prehistoric Plains Indian history, culture, and other scientific topics remains enormous.
