30 million years old Rocks.

I took this picture when we were in a bus tour to see bears. We were not lucky- didn't see the bears, but tour guide told us this rock is more than 30 million years old.

Fishing Cone

Native American used to cook fish inside that cone which has hot water.

Chipmunk

You can see chipmunks everywhere in the park. They are tiny than what I thought.

Spring in Yellowstone

Lots of springs and geysers in the park.

Yellowstone Lake-2

Fishing Bridge

Despite the name Fishing Bridge, angling has been prohibited since 1973 to protect native cutthroat trout. Today it is a wonderful place to observe fish. We didn't get chance to see fish because we tried to get on the bridge at 3rd times to avoid rain. Water in the river is so clear.

Yellowstone Lake

Unfortunately it was raining when we were there. Yellowstone lake surface area is twice as big as Washington D.C which is 69 square miles.
