Geysers of Yellowstone

What an unbelievable place. The land is steaming everywhere you look.  The colors from the bacteria are vey vibrant and the smell can be pungent.

This one is called Dragon's mouth because it used to spew water high in the air and the movement of the water in the cavern sounds like a roar.

Mud pots that used to cover tourists with a mud bath.

An example of the colors from bacteria. Geyser at Mammoth Hot Springs.

This looks like snow, but it's not. Obviously there was a fire here.

We found a favorite swimming (?) place just north of Mammoth Hot Springs where the river is both hot and cold. The water from the geysers run into the river, so one second the water's cold, the next second it's very warm. Here's Barbara experiencing the temp. changes and my new friend, Rebecca from New Jersey, who showed me how to navigate the river while crawling on my stomach. The current was so strong that floating on your back brought you back down river immediately. Great fun!

Our next stop was Steamboat Geyer. It still erupts, but very infrequently.

Lunch by the river.

Here's an interesting one.

This one's called  Artists Paintpot. Aptly named.

Below are pictures from the Grand Prismatic Spring. This is the largest hot spring in the park. The world's most impressive collection of thermal features. Unfortunately, the day we were there the wind was blowing very hard covering up most of the it.
