Emmons Glacier is a glacier on the northeast flank of Mount Rainier, in Washington. It is the largest glacier (by area) in the continental United States, with a surface area of 4.3 square miles (11 km2). Image File history File links Mount_Rainier_from_Sunrise_bw. ...

In the 1930s, the glacier was found to be receding quickly. However, in 1963, a rock fall from Little Tahoma Peak covered the lower glacier with rock debris. The debris cover insulates the ice from melting. As a result of decreased melting, the glacier advanced rapidly in the early 1980s. That advance continues today, but at a slower rate. Ice beneath the rock debris is melting irregularly and forming a vast hummocky area. // Events and trends The 1930s were described as an abrupt shift to more radical lifestyles, as countries were struggling to find a solution to the global depression. ... 1963 (MCMLXIII) was a common year starting on Tuesday (link will take you to calendar). ...

Emmons Glacier is often used as a route to climb to the summit of Mount Rainier which is called Columbia Crest.

The glacier is in constant motion, and the ice in the accumulation zone flows down to lower altitudes, which is called the “ablation zone”.
The smallest glaciers on Mount Rainier are cirque glaciers.
While the response of each glacier depends on its local conditions, glacier loss seems to be largely the result of a regional tendency toward warmer weather, resulting in less snowfall and high rates of ablation (the loss of snow and ice by melting).
