Look Into My Eye....
An almost mesmerizing deep blue thermal pool at West Thumb Geyser Basin. Dunno how deep it is, but the clarity of the water makes it difficult to judge. Usually, the pools ended up being a fair bit deeper than any of us guessed.
The late day sun was throwing long shadows and gave parts of the basin, which we mostly had to ourselves, a really neat mood.
Another good ol' fisheye shot.
