BLM WYOMING KNOW BEFORE YOU GO

The BLM welcomes you to explore, enjoy, and make positive memories from your outdoor experiences on America's public lands and waters. Please remember these are wide-open spaces and wildlands. Plan ahead and be aware of potential hazards. It is everyone's responsibility to take the necessary steps to minimize chances of becoming lost or injured on public lands.

When visiting public lands, please also practice Leave No Trace and Tread Lightly principles.
