On November 24, 1805, the Corps of Discovery, led by Captains Meriwether Lewis and William Clark, votes to spend the winter on the south bank of the Columbia River. All members of the expedition are allowed to participate. This is the first election by Americans in the West, and the first election to include a woman, a Native American, and an African slave.
The Corps arrived at the mouth of the Columbia on November 15 and built Station Camp on the north bank of the river. On the November 24, the captains put the issue of where to spend the winter to the entire company, an unusual step for an Army unit. Included in the vote are Sacagawea, the Shoshone wife of one of the expedition's hunters, and York, Captain Clark's African slave. The group decides to leave the wind-swept Station Camp and to find more sheltered quarters on the south side of the river.
