Getting started with the Miles City plat map

Opening the official parcel viewer
Your first stop is the Montana Cadastral; it covers each tax parcel from Ismay to Kinsey. Without an address in hand, pan along the nearest road until the lines appear, then click inside the one you want, which applies near Ismay as much as anywhere. For a parcel near Ismay, the parcel card usually lists the owner of record, assessed acreage, the parcel number and sometimes recent sales.
Getting your bearings
