[1] The elementary school district includes the census-designated places of Gardiner, Corwin Springs, and Jardine.
The high school district also includes Cooke City and Silver Gate.
At the time, a lack of transportation options made it difficult to send children in Mammoth to the school in Gardiner.
In the years prior to 2008, with improved transportation options, some Mammoth children went to school in Gardiner even though there was a school in Mammoth; at the time Wyoming did not have an agreement to send money to Montana for the education of those children.
Circa 2008 the interstate agreement to send money was made, and by then fewer children were in Mammoth.
