Thermal Features of Yellowstone

The thermal features were the impetus of my desire to go to Yellowstone.  They seem to create scenes from a Sci-Fi movie.  It feels like being on another planet.Thermal Feature

Did you know half of the worlds geysers are found in Yellowstone?

And Yellowstone sits atop a massive super volcano that fuels the hot springs, geysers, and fumaroles?  Magma is usually deep underground but scientist believe that in the caldera of Yellowstone the magma is a mere 3 miles beneath the Earth’s surface.

Old Faithful

Old Faithful is of course the most famous thermal feature.  It’s of impressive size, predictable, and close to the gift shop, lodge, and inn.   Standing around with lots of people and the temperature just above freezing in a light rain to watch it for the first time was sort of anti-climatic.  Watching from the lodge while drinking a cup of cocoa was an improvement.  Sitting outside under a full moon watching Old Faithful with my family was close to perfection.

Morning Glory

Although the ranger said Morning Glory isn’t as vibrant as it used to be, it is still well worth the walk.  The colors are caused by thermophilic bacteria.  You can actually tell the temperature of the water by the color.

Chromatic Pool

I thought Chromatic Pool was interesting.  Doesn’t it seem like a scene from Star Trek or something?

Stinky Mammoth


The terraced springs at Mammoth were unique and fascinating but stinky.


Firehole Drive 1


We were really glad we took the scenic Firehole Drive.  We saw 3 or 4 geysers erupting.  If I remember correctly this was toward the end of a day when the kids had already walked 10 miles so they were thankful to have so many geysers close to the road.

This was a really incredible trip!  I’m so thankful we finally made it a reality and I’m super thankful to Scott for taking so many pictures for me to share.
