Pikas are fluffy rodents that live at high altitudes across the West. The animals squeak when danger nears. The squeaky fluff-balls are considered indicators of climate change because they’re so sensitive to heat. Scientists say they have found some of animals in Colorado’s Rocky Mountains are behaving strangely.

Jessica Castillo Vardaro, a wildlife biologist with the University of California, Berkeley, studies pika genetics, a field that can involve some unusual data collection methods.

According to the Western Governors Association, species like the Canada thistle and common carp aren’t just nuisances -- they’re a matter of western biosecurity.

Dozens of young children were reunited with their parents yesterday after being separated at the border under the Trump administration’s “zero-tolerance” immigration policy. The government is still working to reunite many more children with their parents, some of whom are being held at a detention center in Aurora, Colorado.

One of the world’s biggest firefighting aircraft is based in Colorado Springs. But it's fighting fires in California right now, rather than in the Mountain West.

In an open field in Longmont, Colorado, about a dozen people crouched in the tall grass, moving slowly and deliberately through mud that squelched underfoot. Some carried huge, serrated knives called hori-hori, a Japanese tool made specifically for gutting weeds. Others wielded gardening shears, saws or chemical sprays as their weapons of choice.

Between growing populations and changing climate conditions, our water sources are only expected to get more crunched. Communities in some very dry states have had to get creative about where to get their water, sometimes purifying sewage into drinking water. More western cities are beginning to get on board, too. But there’s a problem: the ick factor.

Nuclear testing during the Cold War sent radioactive fallout far away from the actual test sites. Politicians are moving to expand who can be compensated by the government for getting sick after exposure to that fallout.

A study in the journal Science says a lot more methane is leaking from oil & gas sites than previously thought -- about 60 percent more than the current estimate from the Environmental Protection Agency.

Public lands have been in the news a lot this year. They comprise much of the Mountain West, from around 30 percent of land in Montana and Colorado to more than 60 percent in Utah and Idaho. This summer, we’re taking you on a tour of some of our favorite public lands.

The fossil skeleton of a carnivorous dinosaur recently found in Wyoming was just auctioned off in Paris. Paleontologists are worried the sale is part of a trend that will keep specimens from our region out of the hands of scientists.
