The Sheridan County Chamber of Commerce does not sell land owner maps.

Map books can be purchased from the county FSA office. Their phone number is (406) 765-1801

You can also use the OnX app, which gives you lot lines & owner contact information. It's recommended to download the maps before you head out for the day as mobile service is spotty

At this time, the chamber does not have any active members for Lodging, but a google search will return other options in the area. It's suggested you search by city (Plentywood & Medicine Lake) as Sheridan County may return businesses in Sheridan, MT or Sheridan, WY.
