Admiral Byrd returned to Antarctica and spent the first ever winter over in the interior of Antarctica, alone, at Advance Base 120 miles south of Little America. Byrd made daily weather observations but became very ill when carbon monoxide leaked from a faulty stove. Three men: Tom Poulter, Amory Waite, and Pete Demas traversed 120 miles to Advance Base in the dark of winter and in temperatures as low as -70 to nurse Byrd back to health and fly him back to Little America
