The Idaho Building for the 1893 Chicago World's Fair was a rustic-design log construction designed by architect Kirtland Cutter.
[2] The structure stood on the extreme north line of Jackson Park, over a mile and a half from the Forestry Building, which it recalled.
It was built entirely of native materials consisting of a log house on a foundation or basement of lava and basaltic rock.
The shakes on the roof were held in place with heavy rocks and withstood the great Chicago gales.
The arched stone entrance seen in the picture opened into a large room, at the end of which was a stick fireplace with a log mantel.
