Upper Geyser Basin, Midway Geyser Basin, Fountain Paint Pots – May 27

Getting back to what may be the best national park in the country just couldn’t wait very long. Here are a few photos from my second trip to Yellowstone National Park. This is just a tiny collection of the 10,000+ geothermal features in the area.

Upper Geyser Basin – Old Faithful Area

This first photo is of Shield Spring. Notice how thin the crust is right around the edges of the water. This is why it’s important to stay on the boardwalks, because you can and will fall through if you get too close!

Castle Geyser is a larger geyser, erupting up to 90 feet every 10-12 hours.
