Yellowstone experiences thousands of small earthquakes every year, virtually all of which are undetectable to the  tourists. The park contains the largest active geyser in the world. There are 300 geysers in Yellowstone and a total of at least 10,000 geothermal features altogether. Half the geothermal features and two-thirds of the world's geysers are concentrated in it. The park has over 290 waterfalls, Yellowstone Lake is the largest high altitude  lake in North America. Hot springs and chromatic pools are one of the most photographed areas of the park.
