Camping
In remote locations, mountaineers will set up a "base camp", which is an area used for staging attempts at nearby summits. Base camps are positioned to be relatively safe from harsh terrain and weather. Where the summit cannot be reached from base camp in a single day, a mountain will have additional camps above base camp. For popular mountains, base camps may be at a fixed location and become famous. Examples include the Everest base camps and Camp Muir.
