“Large amounts of snow fall on the surface late in the summer and quickly insulate the water from the subfreezing air temperatures above, allowing the water to persist all year long,” said Rick Forster, lead author and professor of geography at the University of Utah.

The arctic cold front brought subfreezing temperatures, snow, freezing rain and treacherous driving conditions.
