Importance of sublimation for the Rocky Mountain snowpack highlighted in study

This past winter, the Rocky Mountains experienced an historic snow drought, a worrying development for the tens of millions of people in the arid American West who depend on snowmelt for water. Now, a new study in the journal Geology investigates the geologic history of a surprising process that might be making the problem even worse: sublimation, the process by which frozen water transforms directly into water vapor, skipping the liquid phase altogether.
