Unfortunately, this is a good way to decrease the groundwater supply, lower the water table, and dry up the geyser field. The hot water of geyser fields contains dissolved minerals. These precipitate to form solid minerals at the geyser vent, because the water there cools on contact with air and thus can no longer hold as much mineral matter in suspension. It's important to stay on boardwalks in geyser basins, because the crusts of travertine or other rock that form can be thin, and people can fall into hot springs and . . . The bacteria that live in extreme environments may resemble bacteria that speculatively live beneath the surface of Mars, as suggested by shapes seen in a meteorite that came to Earth from Mars.
Terraces form where hot springs seep out along a hill slope.
They are built by rock that precipitates from the hot springs water. There are bear, elk, and buffalo in the park. The canyon of the Yellowstone River has a V-shape. It exposes Precambrian rocks in the footwall of a large normal fault. The basin is the hanging wall.
