Donner Party

 The Donner Party was a group of American pioneers who set out for California in a wagon train. Delayed by a series of mishaps, they were snowbound in the Sierra Nevada mountain range from November 1846 to February 1847. Some of the emigrants resorted to cannibalism to survive, eating the bodies of those who had succumbed to starvation and sickness. The journey west usually took between four and six months, but the Donner Party had been slowed by following a new route called the Hastings Cutoff across Utah's Wasatch Mountains and the Great Salt Lake Desert. They lost many cattle and wagons in the rugged terrain, and divisions formed within the group. Their food supplies ran low after they became trapped by an early, heavy snowfall high in the mountains. In mid-December some of the group set out on foot and were able to obtain help. Of the 87 members of the party, 48 survived to reach California. Historians have described the episode as one of the most spectacular tragedies in California history.
