A menace lurks beneath the snow high up in the southern Rocky Mountains.
At first glance it seems innocuous, another piece of a dynamic alpine ecosystem, certainly unable to cause the cascade of problems scientists say it could. How could something so simple undermine our water infrastructure, stress wildlife and lengthen the wildfire season all at once?
