30 Unusual Archaeological Finds In The US We Still Can’t Explain

28. BISONS GALORE

Excavations at an archaeological site in the Fincastle Grazing Reserve, north of the Montana border, revealed about 200,000 fragments of bison bones in a pit. Ancient hunters used the site as a hunting ground and dates revealed it to be about 2,500 years ago. Archaeologists say the hunters may have hunted the animals in a single event. Archaeologists can’t figure out the elaborate display and placement of the bison bones, but one theory of its function is ceremonial offerings.

27. THE OLDEST FOOTPRINTS IN AMERICA

Fossil footprints are always exciting because they show the paths of ancient humans and in British Columbia on the shoreline of Calvert Island, 13,000-year-old footprints were discovered. The discovery suggests ancient humans from Asia entered America by the coastline and that they were seafarers who used boats to explore islands. The 29 prints uncovered may have been from two adults and a child. The footprints reveal that America had human occupation during the last ice age, but it doesn’t explain the human activities or movement.
