Truncated spur

Truncated spur

A truncated spur occurs when the action of a glacier does not follow the original course of the river that wound round interlocking spurs, but, as the force of a glacier is much more powerful and cannot flow as freely around corners, it can carve its way though the rock cutting off the edges of interlocking spurs to form truncated spurs. Hanging valleys are found in between truncated spurs from a side view as the Hanging valleys join the main glacier from an angle.

Artificial truncated spur are vastly becoming more popular. They provide good shelter for locals, and good habitat for animals.
