Federal shutdown reduces Yosemite rangers, leading to surge in illegal climbs, BASE jumping, and squatters.

Amid the ongoing federal shutdown, Yosemite National Park has seen a rise in illegal activities including squatters in campgrounds, unauthorized Half Dome climbs, and BASE jumping from El Capitan, attributed to reduced ranger presence. Videos show climbers bypassing checkpoints and jumpers defying long-standing bans, raising safety concerns as emergency response is limited. While Grand Teton and Yellowstone report fewer issues, officials warn that the full impact of reduced oversight—such as environmental harm or accidents—may emerge later, despite some essential staff remaining on duty.
