A black helicopter swoops past a group of wild horses running across western Utah’s high desert. It’s mid-morning and already hot.
Lisa Reid, a public affairs specialist for the Bureau of Land Management, is watching the action while sitting on a blanket under an umbrella. The chopper swoops past the herd again, trying to move them towards a corral.
“The helicopter works like a sheepdog,” she says. “It works the horses from side to side, guiding them in the direction it wants them to go.”
