In 1907, Seton and the naturalist Edward Alexander Preble verified a claim from ten years earlier by the frontiersman Charles "Buffalo" Jones that Jones and his hunting party of musk oxen had shot and fended off a hungry wolf pack near the Great Slave Lake in Canada.
Seton designed and built his castle as a 32-room, 6,900 square foot (640 m2) multi-level building with a flat-roof and rough hewn stone wall exterior.
