The springs, geysers and steam vents are scattered over it in the most irregular fashion.
The geysers and other hot springs are due to the same causes as the active volcanoes, and the earthquakes are probably manifestations of the same forces.
The volcanoes have long been extinct, but the diminished energy now causes hot springs and geysers in all parts of the plateau, about loo in number.
The silicious matter has also built up around the springs and geysers cones or mounds of considerable size and great beauty of form.
But the low temperature causes the moisture-laden winds to deposit here greater quantities of rain and snow than in the semi-arid regions below, which not only promote the growth of vegetation, but cause the activity of the springs, geysers and waterfalls.
