"It is history, travel, anthropology, geography, journalism, confession, memoir, natural history and autobiography. It is the life and times of Chase County, and incidentally everything you need to know about Kansas." So wrote Paul Theroux in his New York Times review of "PrairyErth (A Deep Map)" when it was published in 1991. The second in a trilogy of travel narratives by Missouri native William Least Heat-Moon, "PrairyErth" went on to spend three months on the Times bestseller list.

Now, to mark the 20th anniversary of its publication, Steve Kraske is joined by Heat-Moon for a conversation that revisits Chase County, Kansas. They'll discuss the author's journey in creating a work The Chicago Sun-Times called "our modern day Walden" and talk about the changes that have come to that area of tall grass prairie in the two decades since.
