A group of climbers, some who used to work for the Park Service, intended to raise awareness about how recent federal job cuts could threaten the country’s parks.

Flying the American flag upside down is often done during times of distress or unrest. An American flag was hung upside down over El Capitan in Yosemite National Park over the weekend to protest the firings of federal staff by the Trump administration.

The flag was reportedly hung over the side of El Capitan as a sign of protest by Yosemite employees concerned about the recent downsizing carried out as part of the Trump administration’s cost-cutting initiatives.
