Looking for a Cass County plat book? Plenty of people around East Gull Lake still want a paper atlas with owner names on every section. We'll cover what's in one, where Cass County copies turn up, and how the county's free map fills the gaps.
What a Cass County plat book is
A plat book, sometimes called a land atlas, displays each township in Cass County as a page, with ownership blocks labeled by owner name and rough acreage. Deeds and recorded plats, not the atlas, still govern land near Ah-gwah-ching in the county.

Current and older editions
Try the library in East Gull Lake or a local historical society for older Cass County editions; libraries sometimes keep past atlases for reference. Collectors and genealogists prize old Cass County atlases as they show farm names and owners near Ah-gwah-ching long before online maps.
What a plat book page displays near Backus
