For such a colorless, small feature, I find this one fascinating and have several pictures. The water is crystal clear and the little terrace is smooth and white. The water doesn’t so much splash as burble.
Bluebell Pool and Seismograph Pool are right next to each other and are notable for their temperature difference. Typically Bluebell is blue (of course) and Seismograph is green/yellow/orange. In 2010, both Bluebell and Seismograph were blue.
I like to take pictures of Dragon’s Mouth Spring, but it is not easy. The pool boils at the opening in the hillside, putting out a steady steam cloud. If it doesn’t obscure or fade the colors, it messes up the exposure settings. So this one is another of my drive-by features. I drive by, hop out, take a few pictures and then check them out when I get home.
