Frederick Philip Grove,
Over Prairie Trails
“ And again the snow was thrown up into a bulwark, twenty and more feet high, with that always repeating cliff face to the south, resembling a miniature Gibraltar, with many smaller ones of most curiously similar form on its back: bulwarks upon bulwarks, all lowering to the south. In these the aggressive nature of storm-flung snow was most apparent. They were formidable structures; formidable and intimidating, more through the suggestiveness of their shape than through mere size. ”
