upper geyser basin - Trent Sizemore

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!

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.

Crested Pool is one of the more colorful features, with the sudden change from orange to blue. This is one of my favorite features in the Upper Geyser Basin.

Depth: 42 feet

Temperature: 199 F +

Belgian Pool was once named Oyster Spring, but was renamed when someone from Belgium fell in and died in 1929.

Depth: ?

Temperature: 151-180 F

The size and color of Morning Glory Pool, on the north end of the Upper Geyser Basin make it well worth the walk to get there.

Depth: 23 feet

Temperature: 157-162 F

Midway Geyser Basin

North of the Upper Geyser Basin is the Midway Geyser Basin. The grounds surrounding Grand Prismatic Spring are painted with more unusual colors than one could possibly imagine.

Depth: 160 feet

Temperature 160 F

Discharge: 550 gallons/minute

The Firehole River is the final stop for water from many of the parks thermal features.
