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:
“It had not a New England but an Oriental character, reminding us of trim Persian gardens, of Haroun Al-raschid, and the artificial lakes of the East.”
—Henry David Thoreau (1817–1862)
“The line it is drawn
The curse it is cast
The slow one now
Will later be fast
As the present now
Will later be past
The order is
Rapidly fadin’.
And the first one now
Will later be last
For the times they are a-changin’.”
—Bob Dylan [Robert Allen Zimmerman] (b. 1941)
