A rare mountain tornado touchdown on the side of Mount Evans just west of Denver Colorado. The twister was short lived but quite a sight considering most funnels form over flat land.
The National Weather Service did confirm the funnel to be a real tornado, even though it was short lived.
The tornado touchdown occurred at roughly at 11,900 feet, making it the second highest tornado in the United States. The highest tornado ever recorded in the United States occurred on July 7th in the Sequoia National Park in California, at 12,000 feet elevation.
