The homes we visited were spacious and made of wood when it was available in the region. Some you entered through a door. Some through a Z-shaped tunnel to keep the heat in and bears out. Some you entered through the roof. One of the homes had loose wood panels. In the wet season, the wood would swell and form a tight seal keeping the heat in. In the dry season, the panels could be separated for air conditioning.
My personal favorite was the fish wheel. The young tour guide said that it is illegal to use one because it would scoop up so many fish. Now residents of Alaska can dip net. They can wade out into a river where the salmon are gathered and just scoop them up with a net. Not sure what the limit is.
Enjoy the photos.
