The Big Flat Community Grain Bin began as the result of community meetings that were held in 2008 to explore the possibility of creating a grocery store cooperative. At that meeting, other challenges were discussed regarding ways in which to develop the geographic area known as the Big Flat surrounding Turner and Hogeland, Montana. While the grocery co-op would culminate several years later, preparations immediately began for formation of a 501(c)(3) non-profit foundation with the intent and purpose of supporting the school and the community, as was expressed in community surveys held at that time. Fundraising began for the filing fees needed for the IRS application, and strategic planning took place.

Formal paperwork was filed in November of 2011, and in May of 2012, just prior to the Turner Centennial Celebration, the Big Flat Community Grain Bin, Inc. received official notification of its acceptance by the Internal Revenue Service of its 501(c)(3) non-profit status. Since its infancy, the BFCGB has taken the first steps down a long road toward sustainability of the school and the Big Flat.
