Last week we visited one of the bluff shelters along the White River excavated in the 1920s by archaeologist Mark Harrington. From this work, Harrington concluded that there had been a distinct native American culture he called the Ozark Bluff Dwellers. While that notion is no longer considered valid — these were Caddoan people using the bluffs but they interacted with the larger Caddoan society — it still makes an interesting story. The bluff shelters Harrington visited are difficult to find — some may be inundated by Beaver Lake — but we can access this one through a friend’s lake property.
