Mt. Jefferson

Mt. Jefferson hosted six glaciers of which four are consistently named on  U.S.G.S. maps (see map at left). Going clockwise around the peak from the south aspect, these are:

• Timberline (unofficial)

• Milk Creek (sometimes named)

• Russell

• Jefferson Park

• Whitewater

• Waldo

​

The extent of glaciers on Mt. Jefferson is based on photographs from the 1950s. Lower at left is a satellite image from September 2021 showing the current extent of ice. 

 

Of Mt. Jefferson's glaciers, two have fully vanished: Timberline and Milk Creek. Milk Creek was on the west side of the volcano (see snow patch on topographic map); Timberline was located south of Waldo Glacier reaching near the tree line.

 

Waldo Glacier is becoming quite small and stagnated as of 2023.

​

Whitewater Glacier is still quite large but is breaking up into several smaller glaciers, meaning its name as one glacier may need to be changed in the near future.
