A group of U.S. Geological Survey scientists scraped and studied the inside of a freshly dug trench just off the Rainbow Lake Trail near Frisco in search of evidence of mountains moving.

New research shows that wildfires – especially intense ones – can raise concentrations of toxic forms of mercury - including its more toxic form methylmercury - in waterways.

Over the last 30 years, concentrations of toxic metals like zinc and copper have doubled in some of Colorado’s high mountain streams. Researchers blame climate change.

Across the Western bumblebee's range, populations declined 57% from 1998 to 2020, according to a study published last month in the journal Proceedings of the National Academy of Sciences.

In 2018, the U.S. Geological Survey and several Western states formed the Corridor Mapping Team, a collaboration among state and federal wildlife biologists to map ungulate migrations. Last week, the team published its first volume of maps, which document more than 40 big-game migration routes in Arizona, Idaho, Nevada, Utah and Wyoming.

The lab going up in Boise, Idaho, will be part of a new, larger U.S. Geological Survey building. And it would test environmental DNA, or eDNA, from around the nation. That is, instead of trying to find an invasive animal, like a single mussel or fish in a lake, scientists could just sample water to test for DNA of certain species.
