1847: The first group of rescuers reaches the Donner Party, who were starving and feeble, turning some to cannibalism to survive. Weather conditions were so bad that three rescue groups were required to lead the rest to California, the last arriving in March. Forty-eight members out of an original group of 87 ultimately survived to live in California.
