This series explores the Yellowstone National Park and its caldera which sits just below the earth surface. Here, volcanic water and gasses escape to the surface above to create various geysers, hot springs, fumaroles, and mud pots. The water is teeming with thermophiles (bacteria that can survive in higher than normal temperatures). These thermophiles are what create the various red, yellow, green, orange and brown colors along the edges of various thermal pools or where the water drains out and creates the perfect tempered living conditions.
The water in this area contains high levels of silica which, when dried, create sinter in various complex patterns. The sinter, combined with the thermophiles, create fascinating compositions whose colors change season to season and year to year based on water, sunlight, earth movement, etc. The depths and temperatures of the various pools create vivid blues and aquas which contrast beautifully with the other yellows, reds, and oranges.
Taken as a whole, each thermal feature is fascinating and beautiful in its own regard, but I prefer seeing the abstract intricate details which hint at the complexity of this every changing environment.
