It is a common theme in my photography to reach out and capture the "other worlds" on ​Earth.  My recent trip to Yellowstone National Park in Wyoming (USA) gave me plenty of opportunities.

Home to two-thirds of the world's geysers, Yellowstone is a place of extremes.  Gooey, bubbling mudpots and spectacularly colourful hot springs.  Impressive canyons and remarkable wildlife.  Situated on what is essentially​ a "supervolcano," Yellowstone is best known as a hotbed of geothermal activity.

​Here, the bubbling hot water heads toward the edge of Yellowstone Lake.
