snowlines
Mountain frost borders
Snowlines are the boundaries on mountains or at latitudes above which snow remains year-round.
The snowline varies by location—near sea level at the poles, thousands of meters high near the equator.
Climate scientists track shifting snowlines as indicators of warming: Alpine snowlines have retreated significantly over the past century.
