Yellowstone, the first National park in USA, was established in 1872 and covers three states: Idaho, Montana and Wyoming. Its enormous volcano inspires awe with its geysers, calderas, hot springs, mudpots and fumaroles.



Yellowstone has the world’s largest collection of geysers.

Although the last volcanic eruption was 640,000 years ago, the active magmatic heat still powers astonishing geothermal power. As we drive through the park, we are fortunate to encounter black bears, moose and many herds of bison and elk.

At the Norris Geyser Basin, each year new hot springs appear and others become dormant. Many of the geysers are acidic with temperatures reaching 200F(93C) degrees. many of the beautiful colors of the caldera are evidence of thermophilic microorganisms.

Yellow deposits contain sulfur which is used by the thermophiles for energy. Red deposits contain iron while emerald green color contains chlorophyll from the algae living there.

Beneath the park the partially molten magma heats the water and forms geysers.

Steamboat Geyser is the world’s tallest  geyser erupting more than 300 feet (91 meters).

Old Faithful is the most iconic Geyser
erupting every 60-110 minutes
around the clock, as high as 180 feet (55 meters).








Yellowstone is the most geothermal hot spot on Earth

The hot springs in the park do not have an erupting activity but rather flow freely flow to the ground.

Mammoth Hot Springs contain limestone and other sedimentary rock. The travertine terraces build up rapidly and shapes change often. View the video we took from Mammoth Hot Springs.

We also drive to the Yellowstone Grand Canyon with its beautiful Artists Point, Uncle Tom’s trail and Lower Falls. The Artist Point is one of the most photographed views in Yellowstone, with its river framed by colorful canyon walls.

The Iconic Grand Prismatic is the largest hot spring in the US and third largest in the world.

Grand Prismatic Spring is located in Midway Geyser Basin, its vivid colors resemble a rainbow: red, orange, green, blue. The microbial mats around the edges produce its unique colors due to the mineral rich hot water while the center has its intrinsic blue water color.



Yellowstone National Park is a nearly 3,500-sq.-mile area atop a volcanic hot spot. Mostly in Wyoming, the wilderness park spreads into parts of Montana and Idaho in USA


Just outside of the park at the Western Entrance, we stopped at the small city West Yellowstone to enjoy local hearty, home-made meal and listen stories by friendly locals about wildlife adventures.
