'Thor's Well' in Oregon, USA - The Pacific Gateway to the Underworld! Thor's Well is a salt water fountain driven by the power of the ocean tide located in Cape Perpetua (a typical Pacific Northwest headland), Oregon. It is basically a deep hole in the rocks off a rough stretch of the Oregon coastline in the USA. As the waves crash in, it fills up, spouts water 20 feet in the air and overflows, before sucking the water back in and out to sea.
