People have lived in the Pacific Northwest since the Paleo-Indian period, about 11,000 BC. They hunted big animals like mammoths using spears and atlatls, and there were plenty of big animals during this period as the Ice Age was just ending. But people also probably gathered lots of plants, berries, nuts and seeds to eat.
In this area, the Archaic period began around 7000 BC (a little later than in the south) The big animals like mammoth died out about this time, and hunters had to begin to hunt smaller animals like deer and elk, and to fish for salmon. The weather got warmer and some families dug wells to get water. People began to weave mats and baskets and nets and sandals.
About 2000 BC (again a little later than in the south), the people of the Pacific
Northwest entered the Middle Archaic. They still used spears and atlatls
for hunting. But, like other Middle Archaic people further south, they began
to feel a little more crowded on their land, and so they began to fish
more and to gather more of their food. By about 1500 or 1000 BC, people
also began to use fire to increase the amount of food there was to gather.
They would set grass fires or forest fires on purpose to clear out weeds
and underbrush and make more room for animals they hunted and the plants
they wanted to gather. By the end of the Middle Archaic period, around 300
BC, the Chinook people had moved into this area and settled down.
Salmon "running" in the river
In the Late Archaic period, the Chinook lived along the Columbia and Willamette rivers near the Pacific coast (in modern Oregon and Washington). They were hunters and gatherers, and especially fishers, who lived mainly on salmon that they caught in the river during the spring salmon runs and dried and smoked so they could keep it all winter. They also hunted elk and deer, using their new bows and arrows as well as their old spears and atlatls. They gathered and ate acorns, and a lot of camas and wapato, a plant that grew in wetlands, that was a root like a potato.
The Chinook did not have inherited or elected leaders, but lived in small bands with only temporary leaders or "big men". They traded along the Columbia and Willamette rivers and down the Snake River.
Chinook people lived in villages on the high land above the rivers. Their houses were wooden longhouses built of cedar planks. Richer people had bigger houses, and poorer people had smaller ones, but if you were really poor you had to live in somebody else's house. Big houses might have as many as a hundred people living in them. Each family within the house had a separate room with walls of woven mats, and a fire inside the room. But there was also a big fire in the middle of the hall that everyone could meet around. This arrangement was a lot like the way British or Scandinavian people lived at the same time (as in Beowulf for instance), and also like the way the Iroquois lived - that is, it was appropriate for a northern community with cold winters and plenty of wood.
Chinook people looked different from their neighbors, like the Nez Perce, because they flattened the heads of their babies to make them look more beautiful. When a baby was little and her skull was soft, her mother took a wooden board and tied it to her baby's head to flatten her forehead. People thought this made their children more beautiful (or handsome, because mothers flattened boys' heads too), the way people use braces on teeth today.
Instead of moving into the Woodland period, the Chinook stayed with the Late Archaic way of doing things until they were taken over by Europeans in the 1700s and 1800s AD.
