This Acrylic Fridge Magnet Depicts Yellowstone National Park's Riverside Geyser
Yellowstone National Park is one of the great American natural treasures. While many visitors come to see the wildlife and hot springs, it is geysers that are the most spectacular and attract the most attention. The Park has numerous geysers, the most famous of which is Old Faithful. However, despite its name, Old Faithful is not the most predictable geyser in the Park, that honor goes to the one shown on this souvenir fridge magnet: Riverside Geyser. The geyser erupts like clockwork in a predictable pattern every five hours to seven, and continues erupting for twenty minutes. This predictability is due to the geyser's isolation from others of its type, meaning that its steady flow of water is not interrupted by the eruptions of other geysers. The water erupts at a height of about seventy five feet (23 meters) and has a temperature of roughly 82 degrees Centigrade (or 178 degrees Fahrenheit).
The Geysers of Yellowstone Are Due to the Park's Unique Geothermal Location
Yellowstone Park is located on top of a "hotspot," an upwelling of heat from the Earth's core. Normally, the area around Yellowstone would not be prone to earthquakes, volcanoes or geysers as it is far from the faultlines that mark the edge of geothermal plates. However, this upwelling has created a massive source of heat and pressure under the Park. While they are infrequent, this has led to stunningly destructive eruptions several times over the past few million years - the most recent about 70,000 years ago. This form of eruption is particularly destructive, far moreso that eruptions like those on Mt. St. Helens, and would have devastating ecological effects. On a more day-to-day basis, this heat leads to the Park's distinctive landscape of hot springs, geysers and volcanic geography.
