What's inside a county plat book
A plat book, sometimes called a land atlas, lists each township in Colusa County as a page, with ownership blocks labeled by owner name and approximate acreage. Deeds and recorded plats, not the atlas, still govern land near Princeton in the county.
The county map you'll pair it with
The county's own public map is the Colusa County ArcGIS parcel map, built on an Esri ArcGIS web map, and it opens without an account for parcels in Grimes and the rest of the county. Use the search box for an address in Grimes or a parcel number, or simply zoom in and click a tract around Arbuckle. If the official address for the Colusa County, CA map ever changes, our directory page carries the current link for Grimes and the rest of the county.
Where Colusa County plat books turn up
Try the library in Grimes or a local historical society for older Colusa County editions; libraries sometimes keep past atlases for reference. An old atlas can help trace when a tract around Arbuckle split off from a larger farm.
Deeds and plats behind the Colusa County map

Current owners without a printed book

What a plat book page lists near Arbuckle
