Editing Climbing wall (section)

===Compared to outdoor climbing===
Indoor and outdoor climbing can differ in techniques, style, and equipment. Climbing artificial walls, especially indoors, is much safer because anchor points and holds are able to be more firmly fixed, and environmental conditions can be controlled. During indoor climbing, holds are easily visible in contrast with natural walls where finding a good hold or foothold may be a challenge. Climbers on artificial walls are somewhat restricted to the holds prepared by the route setter, whereas on natural walls they can use every slope or crack in the surface of the wall. Some typical rock formations can be difficult to emulate on climbing walls.<ref>{{cite web|url=http://www.abc-of-rockclimbing.com/info/indoor-climbing.asp |title=What is Indoor Climbing? |publisher=Abc-of-rockclimbing.com |date=2011-06-02 |access-date=2013-02-03}}</ref>
