When most people are asked to pick the most iconic feature in Yellowstone National Park they are going to say Old Faithful Geyser and it would be very difficult to argue against that, it is far and away the most famous geyser in the park. I might argue though that The Grand Prismatic Basin should rival Old Faithful for that honor.
Grand Prismatic Basin is a true wonder to behold and is a location in the park that should be visited more than once. The colors are stunning and varied and depending on the direction of the wind you will either be rewarded with a jaw dropping scene or a face full of steam. That is why I suggest visiting more than once. :-)
I made this image back in June of 2016 during our family vacation to Yellowstone, and as a point of reference, I was standing very close to where the park ranger is standing in an image I have previously shared.
