Warring Trolls Explanation for Mysterious Basalt Pillars Revised

From EARTH Magazine  -- A complex interaction between lava and water, rather than a fight between mythical troll-beasts of lore, is responsible for the occurrence of rare terrestrial basalt pillars. EARTH Magazine uncovers the truth behind the pillars in the February issue. Despite regional tales of a fight between a pair of angry trolls resulting in the moss-covered basalt pillars, geoscientists from the University at Buffalo have determined that the pillars formed during a rare, nonexplosive lava-water interface during the 1783 eruption at Laki.
