Crazy Mountain Museum

Note that we are closed for the season from Labor Day until Memorial Day!

The mission of the Crazy Mountain Museum is to excite and involve people of all ages and backgrounds in preserving our county's heritage. Since the early 1900's the Sweet Grass Museum Society has worked hard to maintain the history of Sweet Grass County. Our unique museum is a collection of artifacts that have touched the lives of those who have called Sweet Grass County home.

In the 1990's the Society found a permanent home with the building of the Crazy Mountain Museum. The new museum boasts a large research area which includes a master index of over 5,500 surnames of individuals mentioned in a wide variety of documents and pictures within the museum. The index was completed in 2002 when volunteers studied newspapers that dated all the way back to the 1890's.

You are invited to stop by and and view our exhibits and learn more about the events that has help to shape Sweet Grass County and Big Timber into the wonderful place it is today.
