  2. 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.

  3. The Grand Prismatic Spring in Yellowstone National Park, Wyoming, USA.

    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.

    I figured it was Excelsior, but had difficulty with the wireless connection. On holiday in Puerto Rico…took me awhile due to connectivity issues.
