A variation of this formation is a flag tree or banner tree. Branches on the windward side are killed or deformed by the almost constant strong winds, giving the tree a characteristic flag-like appearance. Where the lower portion of the tree is protected by snow cover or rocks, only the exposed upper portion may have this appearance. This is a rather common occurrence in Red Spruce trees of the highest peaks of the central, even southern Appalachian Mountains, and is most commonly seen in the wind-swept high peaks and plateaus of the Allegheny Mountains. This formation most notably occurs with high frequency in the Dolly Sods and Roaring Plains West Wilderness areas along the Allegheny Front in eastern West Virginia, typically occurring at elevations of 3,800 feet (1,100 m) and higher. Trade winds in tropical regions near the equator can also deform trees in a similar manner.

Famous quotes containing the words flag and/or tree:
“There’s an enduring American compulsion to be on the side of the angels. Expediency alone has never been an adequate American reason for doing anything. When actions are judged, they go before the bar of God, where Mom and the Flag closely flank His presence.”
—Jonathan Raban (b. 1942)
“the scythers, Time and Death,
Helmed locusts, move upon the tree of breath;”
—Robert Lowell (1917–1977)
