Oregon Vortex

I'm planning my trip to California in September and I want to stop in Oregon Vortex on my way.
This is the original House of Mystery as you would see it today. It was built in 1904 by the Old Grey Eagle Mining Company as an assay office and tool-shed. This company stopped mining gold in 1911. A few years later this assay office slid off of its foundation on an angle and has been that way ever since. It was not until 1930 that it became known as The House of Mystery at The Oregon Vortex.
