These photos are from Tallac Historic Site at Lake Tahoe. Tallac Historic Site is an area where rich people from California built summer homes starting in the late 1800s. The object in the bottom photo is a refrigerator. The sign reads:

“This icebox is original. The fan was operated by hydro-electric power from Fallen Leaf Lake. Ice was stored behind the mirrored section, and the fan circulated the cold air throughout the other compartments. The triple-paned glass doors allowed folks to see what they wanted before they opened the doors, keeping the cold air inside.”
