Sorry, forgot the time. It was really quick. It took me under 10 min. It seemed obvious that this was a hot springs, a couple geyser pools, or salt flats with some kind of spring feeding the pools. The highway said developed world. The vegetation and land forms seemed to indicate Western North America.

I had a lot of trouble finding this: I thought the yellow meant Sulphur deposits, so I was searching on that assumption. I ended up browsing through the the NASA Earth Observatory, where it was listed.

This only took me a minute or two to locate; I’ve been to yellowstone before and its a pretty unique looking place.

Grand Prismatic Pool in Yellowstone National Park. The coloration is a giveaway that it is a natural spring, most likely in Yellowstone, as it is famous for that.

It’s Pan.
Excelsior Geyser, Yellowstone Natl. Park, Wyoming, USA.
I figured it was Excelsior, but had difficulty with the wireless connection. On holiday in Puerto Rico…took me awhile due to connectivity issues.

This is the Grand Prismatic Spring and Excelsior Geyser in Yellowstone Park’s Midway Geyser Basin. I was lost, but my hydrogeologist father immediately suggested Yellowstone, which made this an unusually quick one.

Grand Prismatic Spring, Yellowstone park.
As with # 51, this also took me some hours because I have never been there and the pictures are rather zoomed in.
