Grand Prismatic Spring, Yellowstone National Park, Wyoming
I paid a heavy price to climb the hill and overlook this gigantic hot spring last fall. My knees were totally messed up after the trip and required fresh cortisone shots. But it knew it would be the last chance in my lifetime to see this fantastic display of nature’s colors.
The Grand Prismatic is the largest of Yellowstone’s hot springs, measuring about 370’ in diameter and over 121’ deep. The bands of colors around the blue pool are created from different species of thermopile (heat-loving) bacteria.
