Plat books vs. recorded plats in Amador County
A plat book, sometimes called a land atlas, shows each township in Amador County as a page, with ownership blocks labeled by owner name and approximate acreage. Don't confuse it with a subdivision plat on file for lots in Sutter Creek; that recorded plat is a legal document, while the atlas is a reference.
