Though,at first, Byrd and his men were able to take a greatmany photographs of the mountains that lay below,they soon ran into serious trouble. At one point, itseemed certain that their plane would crash. Itcould only get over the mountains if it rose to10,000 feet. Byrd at once ordered his men tothrow out two heavy foodsacks.
