switchback
A switchback describes a specific type of zigzagging path designed to make a steep incline manageable. The core image is a sharp, 180-degree turn that reverses the direction of travel to gain elevation gradually rather than climbing a vertical slope directly.
While "winding" or "curvy" roads can be gentle and meandering, "switchback" implies a functional, geometric necessity caused by extreme terrain. It is most commonly used in the context of mountain hiking, skiing, or civil engineering for mountain roads.
When used as a verb, it refers to the act of constructing or navigating a path in this manner. In hiking contexts, "switchbacking" is often discussed as a technique to prevent erosion or reduce physical strain on the climber.
