Antarctic Cuisine: Skua Piles

From Hoosh: Roast Penguin, Scurvy Day, and Other Stories of Antarctic Cuisine, by Jason C. Anthony (U. Nebraska Press, 2012), p. 185:

Skua piles, named for the kleptoparasitic gull, are a USAP tradition and the clearest sign that we are a transient community. Simply put, departing people leave behind their excess stuff in a heap near their dorm recycling area, and arriving people grab what they need for their season. If you're in the right place at the right time, you can find anythings: homemade bookshelves, insulated work clothes, flannel sheets, half-filled shampoo bottles or, less usefully, broken pencils, used batteries, and sex toys. Skua piles are so fundamental to the local culture that "skua" is as common a verb as it is a multipurpose noun. Stuff is skuaed, the wise go skuaing, and so on. Much of the food is condiments people are too lazy to return to the galley or odd items that no one really wants to eat but are unwilling to throw away. I saw the same can of fiddlehead ferns from Maine disappear and reappear over several years. Dusty jars of nearly flavorless spices that I twice claimed, never used, and returned years ago may still be snatched excitedly each summer by a desperate home-cooker. But again, anything is possible in the skua piles; I have stumbled upon rafts of cooking supplies and a new electric teakettle that someone didn't feel like mailing home, as well as quick-cook oats, rice, and other staples there for the taking.
