What mountain pass did the Donner Party take to cross the Sierra Nevada?

The Donner Party took the Hastings Cutoff, which included the ill-fated route through the Wasatch Range and ultimately led them to the Sierra Nevada. They attempted to cross the Sierra Nevada via the Truckee Pass, but heavy snowfall and harsh conditions trapped them in the mountains during the winter of 1846-1847. This decision to take the cutoff ultimately contributed to their tragic circumstances.
