Settlers arrive from Siberia (via land bridge or boat, following the coasts of North America) and/or Europe (by boat via the Atlantic Ocean) in the Paleoindian period (around 10,000 BC). Caribou, deer, and other animals are the primary source of food until the climate warms in 7,000-5,000 BC, bringing more varieties of landscapes, flora, and fauna. Active farming and food preservation begin in the 11th century as the climate and landscape allowed. Native people continue to inhabit the region and maintain the land for thousands of years.
