This rare map showing exploratory routes towards the North Pole as of 1909 includes the routes of Frederick Albert Cook and Robert Peary, each of whom claimed to be the first to reach the Pole. In the conflict that ensued, the courts ruled that Cook's records offered insufficient proof of his claim and awarded the honor to Peary. But a later explorer, Wally Herbert, concluded in 1989 that Peary was mistaken, and that though he came close--within 60 miles--he didn't in fact reach the Pole.
