PLUCKING

Plucking

Plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of bedrock especially large joint blocks. As a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints in the bedrock. The freezing and thawing action of the ice causes cracks in the bedrock through hydraulic wedging. Eventually these joint blocks come loose and become trapped in the glacier.
