Yellowstone has at times been faulted for lacking the iconic vistas that define some of the other US national parks, such as Yosemite or Glacier. However, the ecological variety and ever-changing geothermal landscapes creates iconic scenes that may only last a moment. The trick is to be at the right spot, at the right moment to witness it. And it is because of the fleeting nature of these scenes that make the resulting image more profound; it serves as a reminder of the Earth's transient nature. On a geological scale, this is universally true everywhere, the earth's surface is in constant flux. But on a human scale we rarely have the opportunity to witness this geological ballet. These types of geological changes to the earth are most apparent here than anywhere else in the world.
