fossick

The first people to fossick (in the oldest and still-current meaning of the word), back in the 1850s, were picking over abandoned mining excavations in Australia and New Zealand in search of gold or gemstones. But within a few decades fossick was being used more generally to mean "to search about" or "to rummage." Fossick, as we know it, is a native of Down Under, but it may have its origins in a word known to immigrants from the United Kingdom: the dialect term fussock, meaning "to bustle about" or "to fidget."
