Old Faithful and Other Thermal Features of YNP

Yellowstone NP is known for its many hydrothermal features with Old Faithful Geyser being the best known. At the heart of Yellowstone’s past, present, and future lies volcanism. Huge volcanic eruptions started two million years ago. The latest eruption caused the central part of what is now the park to collapse forming a 30 to 45 mile caldera ( basin). The magnetic heat powering those eruptions still powers the geysers, hot springs, fumaroles, and mudpots.

  1. These pictures still bring a glad exclamation!!! What a sight!!! Thanks for bringing wonderful memories of seeing these close up and personal…

  2. I showed these pictures to Andre, grandson, and told him that we had been there. He wants to know when we are going back to take him! Wish we could.

  3. Don’t know if what I wrote earlier got to you or not–nonetheless, for those of those who have in the past seen this, but now long to see it again….thank you for your beautiful photos…
