A Rock County plat book is the township-by-township atlas farmers, hunters and land buyers around Jasper have kept in the truck for generations. Below is how to track one down for Rock County, MN, and what the online map does better.
What a Rock County plat book is
A plat book, sometimes called a land atlas, displays each township in Rock 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 Kanaranzi in the county.
Opening the Rock County parcel viewer
For land around Hardwick, open the Rock County Beacon site (Schneider Geospatial's Beacon platform); it is the map Rock County itself publishes. Search a Hardwick address on the county search page, read the report, then jump to the map to see that parcel's outline. Our Rock County, MN page keeps the official link and the maps next door to Hardwick in one place.
Where Rock County plat books turn up
Whether a current Rock County edition exists varies, so ask locally in Hills before ordering; county offices commonly know if one is in print. An old atlas can help trace when a piece of ground near Hardwick split off from a larger farm.
Reading a Rock County atlas page
Many atlases add rural residence listings and road maps, handy on back roads near Kanaranzi. Owner names in an older Rock County edition may be decades out of date, so confirm on the county map before contacting anyone near Kanaranzi. Genealogists in Minnesota commonly pair an old Rock County atlas with deed records to follow a farm through the generations.
