The Lewis and Clark expedition explored unmapped territory from the Missouri River to the Pacific Ocean from 1804-1806. The expedition was hugely successful in large part because of the skills and expertise of York, an enslaved person. Though the expedition team was celebrated and richly rewarded, York received neither recognition nor compensation. It wasn’t until 2001, that York’s achievements were finally honored.(Pearson Reading Street, 2010)
