Things To See
Some things to see in Yellowstone is the big geyser, Old Faithful, this geyser shoots very hot water up about 100 feet (30 meters). Other things you can go see in Yellowstone are the Obsidian cliff,this cliff looks like black glass, the indians that used to live here used the rock to make arrow points. Also there are the columns of Sheepeater Cliffs, these columns are made of a rock called basalt, this type of rock cooled quicker than lava so when the lava cooled it left big brown columns with five or six flat sides.
