Answer:
the succession of their own mistakes and poor decisions
Step-by-step explanation:
The Donner Party was a group of pioneers who moved to California from the Midwest. The party was led by Brothers George, Jacob Donner and James Reed. The Donner Party became stranded en route to California in late 1846 because of their poor decision. The party decided to take the new trail called The Hastings Cutoff. They took this route believing it would cut their journey in half. The party was trapped in snow in the Sierra Nevada, and their food ran out.
