The Cahokia Mounds were declared a UNESCO World Heritage site in 1982. Huge constructions built by the inhabitants of an urban complex estimated to have had a population of 40,000 people a thousand years ago, the site amply justifies World Heritage status.
I ask my classes each year whether they know of the site, and fewer than ten percent of my Americans graduate students remember having heard of this, one of only 20 world heritage sites in the United States. Thus a new and popular book on the site and its interpretation is most welcome.
Read the review of the book in the Chicago Tribune.
