The Grand Canyon manages to attract around 5 million visitors a year to Arizona. The canyon, which is almost 450 kilometres long) is a remarkable sight on almost any given day, but some lucky visitors recently have been granted a particularly rare spectacle.
A 'temperature inversion' sees fog and cool air 'sealed' in the canyon by warm air. It typically happens around once or twice a year at the Grand Canyon. However, a 'full inversion' is a much rarer treat, traditionally only occurring once or twice a decade. It's the sort of phenomenon that even park rangers might not experience over years spent working in and around the canyon.
A full inversion occurred on Friday - and, against the odds, visitors enjoyed another yesterday. The Grand Canyon National Park Facebook page described the first as "a once in a lifetime, outstanding, crazy, amazing, mind blowing inversion." Check out some photos and videos below, and the park authorities have been uploading more of the most impressive efforts to their Facebook page.
