The Donner Party ordeal is arguably Truckee's most famous historical event. In 1846, a group of settlers from Illinois, originally known as the Donner-Reed Party but now usually referred to as the Donner Party, became snowbound in early fall as a result of several trail mishaps, poor decision-making, and an early onset of winter that year. Choosing multiple times to take shortcuts to save distance compared to the traditional Oregon Trail, coupled with infighting, a disastrous crossing of the Utah salt flats, and the attempt to use the pass near the Truckee River (now Donner Pass) all caused delays in their journey.
