The number of thermal features in Yellowstone is estimated at 10,000. [1] A study [2] that was completed in 2011 found that a total of 1,283 geysers have erupted in Yellowstone, 465 of which are active during an average year. These are distributed among nine geyser basins, with a few geysers found in smaller thermal areas throughout the Park.
[16] [17] Ninety percent of Yellowstone National Park was covered by ice during the Pinedale Glaciation. [16] The little ice age was a period of glacial advance that lasted a few centuries from about 1550 to 1860. For example, the Agassiz and Jackson Glaciers in Glacier National Park reached their most forward positions about 1860 during the ...
