Proclamation 8947
Establishment of the San Juan Islands National Monument
In simple terms
President Obama established the San Juan Islands National Monument under the Antiquities Act, withdrawing approximately 970 acres of BLM-administered federal lands in Washington State's Puget Sound from development, mining, and mineral leasing. The proclamation mandates BLM management through the National Landscape Conservation System, requires a management plan and advisory committee, restricts motorized vehicle use to designated roads, and protects tribal cultural and religious sites.
