This is the Donnenworth House in Whitehorse, Yukon Territory on the WP&Y RR.
It was built between 1896 and 1905. It was originally a single house with a
canvas tent in the back. They covered the canvas tent with shingles and
added the back part. It is hiastoric as it is the last remaining house retaining
its original canvas and frame materials. Includes nightmode.
