Spirit House is an Anasazi ruin found in the Island of the Sky area of Canyonlands National Park. Sunset light ignites this ruin within a few minutes of setting allowing the earth's shadow to rise in the background distance. These ruins date around 400 to 1200 AD. This ruin is a joy to sit and wait for the setting sun to ignite the grotto, because of the view from the butte to the canyons below.
