Have some GeoNews that doesn't fit in another category? Here's the place. Try to keep it at least somewhat on topic.
People (including myself) tend to forget the origins of the term "Land Mine". Mines in medieval times referred to excavations for the purpose of undermining an enemy’s fortifications. In World War 1, before the age of aerial bombardment and cruise missiles, underground mines were used to plant explosives under enemy lines. In addition to British, German and American sappers that performed these tasks, the Australians had a contingent of miners and geologists who were involved in the Western Front of the War in France and Belgium and were responsible for what was then the largest man-made explosion in history.
