on the Island.

2,164 acres
Protected as a state park since 1977, the island near Big Arm Bay is home to abundant wildlife including bighorn sheep, mule deer, waterfowl, and bald eagles. It is managed by Montana Fish, Wildlife & Parks and lies within both the Flathead Indian Reservation and Lake County, Montana.

For centuries, the Salish-Kootenai used the island to pasture horses and keep them from being stolen by other tribes. The island was part of the Flathead Indian Reservation from the reservation's creation in 1872 until 1904, when the island was divided into individual plots of land. A number of attempts were made towards agricultural development, but none succeeded.
