On 7 July 2004, American backpacker Scott Newton photographed a tornado while hiking in the Rockwell Pass area of Sequoia National Park, California, USA. Airborne debris witnessed by other hikers confirm that the tornado did make contact with the ground. The elevation of the landscape where the tornado was seen is around 3,705 m above sea level, making this the highest-altitude tornado ever recorded to date.
A scientific analysis of the event was published in November 2014 in Monthly Weather Review. The paper’s authors were John Monteverdi, Roger Edwards and Gregory Stumpf.
