Recent glacier quarrying in granite by the
Nigardsbreen glacier, south-west Norway. The side view
(top) shows block displacement along vertical and horizontal
fractures and the rear view (bottom) reveals the effects of
high-pressure water jacking, sufficient to insert water-
rounded boulders into the developing fracture.
