Crevasse trace

A long vein of clear ice a few centimetres to a few metres wide, formed as a result of fracture and recrystallisation of ice under tension without separation of the two walls; these structures commonly form parallel to open crevasses and extend into them. Thicker veins of clear ice resulting from the freezing of standing water in open crevasses are also referred to as crevasse traces.
