The ability to use a map and compass correctly is essential for all winter mountaineers and climbers.

GPS systems can provide a useful back-up to more traditional map and compass skills, and it is recommended that they are used in this way, rather than as the sole navigational aid. Walking on the bearing obtained from a traditional compass will nearly always be steadier than following that from its satellite-driven GPS cousin. The location of the foot of some routes is given by a bearing from a prominent feature for some crags to aid their location in poor visibility.
