The US Tenth Circuit Court ruled this does not constitute trespass in six Western states.; **Unlawful Enclosures Act of 1885:** Federal law prohibits fencing public land or blocking access, yet large landowners effectively control adjacent public squares by denying passage through their property, monopolizing resources like elk populations on public mountains.
