'They won't survive': Trump gas wells would block pronghorn migration route

Conservation groups are fighting the creation of 3,500 gas wells in Wyoming that threaten a 170-mile path

The Path of the Pronghorn is a 170-mile migration route that the antelope-like creatures have traveled annually for 6,000 years. It is one of North America's last remaining long-distance terrestrial migration corridors.

And it is at risk. This week conservation groups filed a legal petition challenging the Trump administration's plan to allow 3,500 new gas wells in south-western Wyoming that would block the route.
