The Table, a 300 m high flow-dominated tuya near Mount Garibaldi, British Columbia. Mathews (1951b) proposed that the Table formed when magma intruded into a vertical pipe in the overlying glacier. The partially molten mass of hornblende-phyric andesite cooled as a large block, with gravity flattening its upper surface. Horizontal columns occur at numerous locations along the periphery of the mass.
