House of Mystery at the Oregon Vortex is at 4303 Sardine Creek L Fork Rd. The House of Mystery, originally an assay office, is located in an area of bizarre, naturally occurring phenomena—the Oregon Vortex. Balls appear to roll uphill, people seem to change from small to large and back again and visitors are unable to stand upright. The phenomena are attributed to a whirlpool of fluctuating energy.
