Musher Leonhard Seppala lived in Nome but traveled over the frozen sea ice of Norton Sound to Shaktoolik, where he picked up the antitoxin for his leg of the relay. When Seppala left Nome, it was -20ºF. In Shaktoolik, the windchill, or temperature with the wind factored in, made it feel 105º colder. What was the windchill temperature in Shaktoolik?
