Exposure (heights)
Exposure is a climbing and hiking term. Sections of a hiking path or climbing route are described as "exposed" if there is a high risk of injury in the event of a fall because of the steepness of the terrain. If such routes are negotiated without any protection, a false step can result in a serious fall.〔Olaf Perwitzschky, Dieter Seibert: ''Bergwandern, Bergsteigen. Alpine Lehrschrift.'' page 71, Bergverlag Rother, Munich, 2008, ISBN 978-3-7633-6032-1((online ))〕

Authors tend to use their own definition of the terms "exposure" or "exposed" when describing routes, for example:
