Monthly images show the approximate amount of snow cover on Mount Rainier, Washington for a full year. The image with the least amount of snow shows the position of the snow line.

Locations above the elevation of the snow line remain snow-covered all year; locations below the snow line alternate between being clear and covered with snow. Examine each frame to find the month with the least snow and identify the snow line.
