There were early signs that this fire season could be a big one, especially the record-low snowpack last winter. In Teton County — near the Grand Targhee Resort — that spurred interest in a novel effort: raising money to help hire a local wildfire mitigation coordinator.

Farmers are navigating an unusual harvest season after low snowpack, March heat, April freezes, and sharply limited irrigation water.

Coal is perhaps most closely associated with Appalachian states like West Virginia, Pennsylvania and Kentucky — or Wyoming, the nation's leading producer of the fossil fuel. But the coal-mining business was once thriving in northern Arizona as well, atop the Colorado Plateau.

Western cattlemen are poised to lose almost all opportunity to comment on oil and gas development underneath their property.

Colorado, Utah, New Mexico and Wyoming are not subject to mandatory reductions; instead, those states are setting up programs to voluntarily conserve water.

Fast, intense wildfires are making it harder for forests to recover and can change the entire ecosystem.

As the climate warms, some mountain trees are moving higher up, while others are spreading downhill. Scientists say something inside the trees may explain why. And that split could reshape watersheds and wildfire risk.

Sunflower sea stars are critically endangered in the Pacific Ocean. University of Washington researchers are working with the Samish Indian Nation to bring this 24-armed creature back from the brink of extinction.

Scientists are flying research missions over northern Utah to understand better how ozone forms and how a shrinking Great Salt Lake, wildfire smoke and other factors affect the state's air quality.

Some living trees in the Uncompahgre measured 9% moisture this summer — drier than the legal limit for kiln-dried lumber. So why did the Gold Mountain Fire leave some whole hillsides untouched?
