🏆 Earth Lodge Village Site — Recreation area on Lake Oahe at the site of historic Arikara earth lodge villages — where Lewis and Clark met the Arikara in 1804
West Whitlock Recreation Area sits on Lake Oahe in Dewey County — at the site of historic Arikara earth lodge villages that once lined the Missouri River. This is where Lewis and Clark met the Arikara people on October 10, 1804 — Clark described their fortified villages of earth lodges and noted their remarkable agricultural skills (growing corn, beans, squash, and tobacco). The Arikara were sophisticated farmers and traders — their villages served as trade centers connecting the nomadic Lakota/Sioux with goods flowing up the Missouri from St. Louis. Dam construction in the 1950s flooded many village sites.

Frequently Asked Questions
What were Arikara earth lodges?
Arikara earth lodges were large, dome-shaped dwellings made of timber frames covered with earth — typically 30–60 feet in diameter and housing 10–20 people. Villages contained 20–100+ lodges surrounded by defensive palisades and moats. The lodges were remarkably energy-efficient — warm in winter and cool in summer.
Were sunflowers domesticated in North America?
Yes — the sunflower (Helianthus annuus) is one of the few major crops domesticated in present-day North America (about 4,000 years ago). Native Americans along the Missouri River cultivated sunflowers for their oil-rich seeds. Spanish explorers brought sunflowers to Europe in the 1500s — they became a major oil crop in Russia before returning to the US as an agricultural commodity. South Dakota is now a major sunflower-producing state.
