How Colorado Cowboys and Conservationists Joined Forces to Stop Drilling

"The drilling leases in a pristine corner of Colorado seemed like a done deal. But then an unlikely alliance of cowboys and environmentalists emerged. And things changed," writes reporter Zoë Rom.

"The members of the group — a self-described ragtag organization that included ranchers, cyclists and snowmobilers — had little in common aside from a desire to protect the expanse, almost a quarter-million acres of public land known as the Thompson Divide. But they ultimately developed a novel legal strategy that helped win a 20-year pause on new oil and gas development across the area.

That strategy could serve as a model for future conservation efforts."

Peter Hart, legal director for Wilderness Workshop, poses for a portrait along Thompson Creek Trail. Hart and his colleagues at Wilderness Workshop, working alongside the Thompson Divide Coalition, learned that the Bush administration’s haste to issue oil and gas leases in the 2000s left them legally vulnerable.

Oil and gas well pads dot the landscape just outside of the divide. Ranchers, cyclists, snowmobilers, and conservationists rallied together against the biggest common perceived threat to their home – oil and gas.
