Viewing Black Sand Basin © 2010 Bo Mackison

Black Sand Basin is a rather isolated group of thermal features in the Upper Geyser Basin in Yellowstone National Park. There are several jewel colored pools and geysers in the area, but I had a hard time concentrating on the specific geysers because the earliest light from the sunrise hitting the steam in 40˚F weather had turned this area, already a Wonderland, into a gigantic, purplish-yellow kaleidoscope of almost unnatural, but dazzling color.

There were only two other visitors at this time of the day, but it was one of the highlights of my three days in Yellowstone. Later, when I watched Old Faithful–the big geyser draw in the park–amongst a noisy crowd of onlookers, I kept thinking I had already seen the real show — at sunrise in Black Sand Basin.
