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:
“What is honor? A word. What is in that word honor? What is
that honor? Air. A trim reckoning! Who hath it? He that died
o’ Wednesday.”
—William Shakespeare (1564–1616)
“What comes over a man, is it soul or mind
That to no limits and bounds he can stay confined?
You would say his ambition was to extend the reach
Clear to the Arctic of every living kind.
Why is his nature forever so hard to teach
That though there is no fixed line between wrong and right,
There are roughly zones whose laws must be obeyed?”
—Robert Frost (1874–1963)
