The mountain was discovered by Lincoln Ellsworth in his trans-Antarctic flight on November 23, 1935, who called it "Mount Mary Louise Ulmer", after his wife. The peak was reidentified by comparing Ellsworth's photograph with those taken in 1959 by the U.S. Navy ...
In the period 1971–75, Ivory Glacier receded 30 m (98 ft) from the glacial terminus, and about 26% of the surface area of the glacier was lost over the same period. Since 1980 numerous small glacial lakes were created behind the new terminal moraines of several of these glaciers. Glaciers such as Classen, Godley and Douglas now all have new ...

Adze-end variations: As with non-ice-tool adzes, those of ice tools vary in several aspects; other ice tools have a hammer head in place of the adze, or are modular, permitting switching styles of adze or hammer, and/or between adze and hammer.
As a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock. The freezing and thawing action of the ice enlarges, widens, or causes further cracks in the bedrock as it changes volume across the ice/water phase transition (a form of hydraulic wedging), gradually loosening ...
