The one and only supported organization is the Yellowstone County Museum. All activities of the Foundation are solely for the sake of the Yellowstone County Museum. The bylaws of the Yellowstone County Museum Foundation Board of Directors state: Article II: PurposesSection 2.1 MissionThe mission of the Yellowstone County Museum is to collect, preserve, and share the history of Montanas Yellowstone River Basin through a range of dynamic educational programs and storytelling exhibitions. Section 2.2 Purposes The purposes of the YCM shall be to: support the maintenance, improvement, and operations of the YCM, protect and enhance the YCMs collections, programs resources, and public trust, ensure all resources and activities support the YCMs mission, collaborate with Yellowstone County and other local governments, community members, and cultural partners, show respect for and respond to the dynamic diversity of local cultures, and seek and procure funding from a variety of sources to financially support the YCMs mission. The organization determined that these activities constituted substantially all of its activities as the organization was established exclusively to support the mission of the Yellowstone County Museum. Each purpose directly furthers the exempt purposes of the supported organization. Part IV, Section E, Line 2b: Reasons For The Organization's Position All of the activities of the Board are key to the Yellowstone County Museum. Without the Foundation Board, the Yellowstone County Museum would not be, or much less, engaged in the maintenance, improvement, and operations of the Yellowstone County Museum and collaboration between Yellowstone County and other local governments, community members, and cultural partners.
