Grassy Butte, ND is in a very sparsely populated area of western North Dakota, in southern McKenzie County. It does not appear in any of the census records back as far as 1960, but it reportedly harbored 100 citizens at one time. Monica Hardy contributed these photos in 2010 with the following comments:
The building that looks like a church in the background of the post office/museum pictures are of a private home. Someone renovated the home. There were other bldgs in the town that had been renovated into private homes. This town is very close to the Theodore Roosevelt National Park… no hotels located in this town at present.
