Here are some photos from my Yellowstone trip on May 31, 2014.
The first region I hit on this trip was the Biscuit Basin, just north of the Upper Geyser Basin and Old Faithful.
This first geyser is Jewel Geyser, which seems to be pretty active, but not huge.
Temperature: 199° F
Height: 10-30 feet
Duration: 60-90 seconds
This colorful feature is the Sapphire Pool, also in Biscuit Basin. The “layers” of different depths showed a deeper shade of blue the farther down you look. The orange surrounding the edges of the pool created a great contrast for the photo below! Sapphire pool was once quiet, but the 1959 Hebgen Earthquake caused the feature to turn in to a 150 foot geyser for about a decade, until it doubled the size of its crater, returning it to this boiling pool today.
Temperature: 200-202° F
Size: 18×30 feet
This brightly colored pool is actually named the Black Opal Pool, also in the Biscuit Basin.
There’s no mistaking this photo as the world famous Old Faithful, in the Upper Geyser Basin! The black storm clouds contrasted well with the white spray and steam of the geyser, making for an awesome black and white finished piece.
The photo below of the Firehole River in the Upper Geyser Basin area does a great job of showing not only the bright colors of the thermal features, but also the scale compared to the visitors!
