YELLOWSTONE GEYSERS A geyser is when molten rock is under the crust near a under ground water source. Then the magma super heats the water. So it tries to expand but it is in a chamber. So then it shoots straight out up to 3 stories tall that’s huge.

YELLOWSTONE HOT SPRINGS Some of the springs in Yellow stone are very colorful. Just like a rainbow with all the different colors. They are hot springs they get hotter the deeper it gets. The outer orange ring is the coolest. Then the others get hotter the deeper it gets. Can you believe that the algae does this. Every color is a different type of algae. And the center of it is to hot for any life.

LOCAL NATIVES In B.C. The Paleo Indians hunted bison using simple but sharp tools. It was a favorite but dangerous tactic. It was to drive the bison off a cliff. With butchers on the bottom and they carved as many as they could. the ones that they didn’t carve where left to rot! Standing in the wrong spot could get you killed.

FOREST FIRES BEFORE AND DURING

FOREST FIRES CONTINUED Change is unavoidable at Yellowstone and not only because of human presence. And in the dry summer of 1988 a tiny fire started in a far corner of Yellowstone. Soon wind and dry vegetation caused more fires to brake out. For several months Yellowstone burned. About 20% of the park was destroyed scientists believe the fires were natural and necessary for Yellowstone.
