Freshwater Mussels Of The Willamette

A large population of native freshwater mussels has been found thriving in an urban stretch of the Willamette. But what do they really tell us about the health of the river?

Drones In Research

A new generation of drones are giving scientists new ways to research the natural world.




The entrance to Snow Dragon cave in January 2012. Note the distinction between so-called "permanent" glacier ice in the foreground and the deep annual snowpack at the cave mouth that would melt each summer. Eddy and Brent made up to seven trips to the caves in 2011 as they began their effort to explore and document the full extent of the cave system.

Return To Mount Hood's Glacier Caves

The spectacular Mount Hood glacier caves that "Oregon Field Guide" documented in 2013 have all but disappeared. But why? Is it global warming, or is something else at play?


Areas of thin ice often formed beautiful skylights in the cave ceiling. When skylights melted out, holes would develop that allowed warm surface air to enter the caves.
Dr. Andreas Pflitsch also identified dozens of warm springs within the caves that reached 78 degrees Fahrenheit. The mixing of cold and hot water created a fog that may also have exacerbated the melting, expansion, and ultimately the collapse of the caves.

What Happened To Mount Hood's Glacier Caves?

The spectacular glacier caves of Mount Hood collapsed and disappeared completely within just a few years of their discovery. Scientists are only now learning what happened.
