Answer:
They had well established winter villages built on the banks of a major waterway. Homes were built partially underground. Some were little round houses with dirt roofs. Some were long lodges. They were both pit-houses.
To build a pit-house, first you dug a pit about six feet deep. Some pit-houses were built for a small family group and perhaps were only 20 feet in diameter. But some were much larger - as much as 60 feet wide and 100 feet long. The small ones were usually oval in shape. The large ones were usually rectangular. But construction of all pit-houses started by digging a pit that was the outline of the house.
Once you had dug the pit, next you piled up rocks to make walls. Then you added some wooden posts to support a roof. Roofs were made of everything from planks to woven reeds. (Baskets and mats were also made out of reeds.)
