I don’t remember even noticing the various geyserite patterns at Yellowstone on my first visit there many years ago, but this visit I spent more time trying to capture some of the amazing patterns I saw than I did taking pictures of the geysers erupting, though none of the shots quite captured the beauty I saw in my head.
Still, I could easily see using some of these shots for screen savers or textures when I get home. I’m particularly fond of the browns and greys, like this one,
and this one,
but this bright orange one reminded me of petroglyphs, and I like petroglyphs a lot.
It almost felt like an alien life-form was trying to communicate with us, probably “Keep off the patterns, stupid!” Despite innumerable signs, you could still see footprints on the areas surrounding the geysers.
This wasn’t caused by archaea like the above patterns, but it also struck me as forming an unusual pattern,
as did grey, black, and yellow lichen growing on nearby rocks.
