A trim line, also written as trimline, is a clear line on the side of a valley formed by a glacier. The line marks the most recent highest extent of the glacier. The line may be visible due to changes in color to the rock or to changes in vegetation on either side of the line.
The term "trim line" is also used for similar looking phenomena caused by floods, volcanic activity, or tsunamis.
Famous quotes containing the words trim and/or line:
“When we think of him, he is without a hat, standing in the wind and weather. He was impatient of topcoats and hats, preferring to be exposed, and he was young enough and tough enough to enjoy the cold and the wind of those times.... It can be said of him, as of few men in a like position, that he did not fear the weather, and did not trim his sails, but instead challenged the wind itself, to improve its direction and to cause it to blow more softly and more kindly over the world and its people.”
—E.B. (Elwyn Brooks)
“It may be the more
That no line of her writing have I,
Nor a thread of her hair,
No mark of her late time as dame in her dwelling, whereby
I may picture her there.”
—Thomas Hardy (1840–1928)
