It’s hard to say when it was exactly that Yellowstone National Park won me over. Maybe it was as I stood shivering in the pre-dawn chill at the Lamar Valley watching a pack of five wolves playing on the ridge; or when I climbed a hill to look down on the magnificent colours and patterns etched into the earth by the Grand Prismatic Springs…

Or maybe it was the enormity of the fact that we were driving and hiking over the largest and most volatile active geothermal area in the Northern Hemisphere!
Yellowstone is sitting above what is known as a ‘hotspot’: where heated molten rock below the earth has been pushed up to linger, bubbling just beneath the surface essentially forming a massive below-ground furnace…2.2 million acres in size.

Yellowstone’s geothermal features are products of all this commotion under the surface: exploding geysers, colourful hot springs, steaming fumaroles and bubbling mud pots.
