The characteristics of boulder problems depend largely on the type of rock being climbed. For example, [[granite]] often features long [[Crack climbing|cracks]] and [[slab climbing|slab]]s while [[sandstone]] rocks are known for their steep overhangs and frequent horizontal breaks. [[Limestone]] and [[volcanic rock]] are also used for bouldering.{{Sfn|Lourens|2005|pp=21-22}}
