Aztalan has remained a mystery since the early nineteenth century when it was discovered by settlers who came to the Crawfish River, fifty miles west of Milwaukee. Who were the early indigenous people who inhabited this place? When did they live here? Why did they disappear? Birmingham and Goldstein attempt to unlock some of the mysteries, providing insights and information about the group of people who first settled here in 1100 AD. Filled with maps, drawings, and photographs of artifacts, this small volume examines a time before modern Native American people settled in this area.

"Visionaries, researchers, curators, and volunteers launched a massive preservation initiative to salvage fast-disappearing immigrant and migrant architecture. Dozens of historic buildings in the 1970s were transported from various locations throughout the state to the Kettle Moraine State Forest. These buildings created a backdrop against which twenty-first-century interpreters demonstrate nineteenth- and early twentieth-century agricultural techniques and artisanal craftsmanship." --Back cover.
