People who grew up near Drummond remember the Granite County plat book as the book that named every farm. Below is how to track one down for Granite County, MT, and what the online map does better.
How to use the Granite County plat book
Private publishers compile plat books from county records, so a county edition is a snapshot of who owned land near Philipsburg the year it was printed. It's different from a recorded plat, which is the official survey drawing for a subdivision in Philipsburg filed with the county.
Opening the Granite County parcel viewer
For Granite County, the free public parcel layer is state-run: open the Montana Cadastral and pan to Drummond. Zoom to Granite County and click a piece of ground near Hall; the summary lists the Montana geocode, owner and acreage. If the official address for the Granite County, MT map ever changes, our directory page carries the current link for Hall and the rest of the county.
Where Granite County land records are kept
The parcel layer for Granite County points back to recorded deeds and plats, kept by the county's recording office (its title varies by state). Easements and access rights near Drummond live in recorded documents, so read the deed, not just the county map.
Towns and land across Granite County

What a plat book page displays near Drummond

Acreage printed in a county atlas is rough; the deed and a licensed survey decide the real figure for a piece of ground near Hall. For a land purchase near Hall, rely on the county parcel record and a title search, not an atlas.
