Weather was a problem in getting up into the air. Luckily before the sun set I got to see Grand Prismatic, the largest hot spring in the park.

Volcanic steam pushes up through the rock to release calcium which forms travertine and the terraces. The process is on going and this scene changes daily. The dark colored stripes are made by "thermophiles" heat loving organisms.
