Lewis and Clark built a small "fort" near Astoria, Oregon, at the mouth of the Columbia River for the winter before they headed back east. This is now a national park, with a reconstruction of the fort based on notes made by the explorers.
This is a reconstruction of a native canoe, similar to one the explorers used in the last part of their journey west.
This is the reconstructed "fort." Basically, it had two rooms for the men who accompanied Lewis and Clark, one for Lewis and Clark, and one for Sacajawea and her husband.
The fireplaces were pretty primitive. No rocks, so there were made of wood with mud plastered on the back.
This is looking up one of the chimneys.
