Yellowstone National Park: Mammoth Hot Springs

Day 2 and another very special day seeing how geology and biology interact!

At some point a sea created the limestone layer at Mammoth Hot Springs, add the super heated water plus the thermophiles and you get a vast stepped, cascading plateaus of travertine stone. As it is being built it is as soft as chalk.

So graceful and beautiful.
