In August 1856, more than 1,000 Mormon emigrants in the Willie and Martin handcart companies left Florence, Nebraska Territory, with plans of reaching Salt Lake City and the headquarters of The Church of Jesus Christ of Latter-day Saints before winter. Their late start, substandard equipment and lack of sufficient supplies had disastrous consequences when they were hit by winter storms. Hundreds died on the journey across what’s now Wyoming and into Utah. Images of emigrant families pulling handcarts have since become an LDS Church icon of the triumph of faith over adversity.
