Cool Facts Lamar Glacier (located in northeastern area of Yellowstone National Park) was created on the Bear tooth Mountains. World’s first National Park 3,472 square miles 96% Wyoming, 3% Montana, 1% Idaho

Glaciations At higher elevations at the mountains, small glaciers assigned to Neoglacial time are moderately active. There were glaciers at Yellowstone but glaciers that were after them came and destroyed them. Glaciers that are known as valley glaciers began at a higher level and slowly began falling down and grew larger creating glaciers known as Piedmont glaciers. ses/Alpine_Glaciation.htm

Volcanic Activity Yellowstone Caldera is known as one of the world’s most extreme volcanoes. A caldera is a volcano in which the top sunk down making a large bowl shape. When it erupted, it was 2500 times more powerful than Mt. St. Helen’s eruption. These powerful eruptions are caused by rhyolitic magma. This type of magma is very explosive /06/yellowstone_it_was.php

Geysers Groundwater trapped in between pores is heated by hot rock Steam is sent upward in the form of bubbles The bubbles clog up the channel tight spots Geyser overflows The pressure increases, and the water begins to boil violently Steam created, forces water out of the vent

Hot Springs Hot Springs are very similar to geysers, the only difference is the fact that a hot springs’ channel is large enough to allow water to circulate. Hot water rises and lets off heat energy by evaporation or hot water runoff. ATTIXS/Mattix%20homepage/studentwork/Lau ra%20Cornelisse%27s%20Web%20Page/Yellow stone%20National%20Park.htm

Steam Vents Cracks in the surface of the ground Pressurized steam from below escapes to the surface orris-tour-black-growler.htm

Mud pots Thermal area where water-saturated sediment is affected by super-heated steam below Steam forces its way up through the mud and groundwater It BURST upward, and the bubbles ‘POP’. allery/mudpot.htm

Fumaroles Similar to hot springs, but there is no liquid water. It is hole or vent where steam rushes into the air oles.htm

Earthquakes Earthquakes in the area change the hydrothermal systems in Yellowstone. Following the shock of an earthquake in 1959, Hegben Lake began to spout jets of water Fumaroles formed near Firehole River, and mud pots began to sprout The earthquake of 1983, has cause Ol’ Faithful’s eruptive intervals to lengthen. lake-earthquake-of/article_dd739bb2-8a2d-11de-a cc4c03286.html

Ol’ Faithful This geyser is one of the main attractions at Yellowstone National Park. People visit from all over to count down the seconds before it erupts. Mathematicians, statisticians, and dedicated observers have analyzed it for many years. america/us/wyoming/yellowstone-national- park/old-faithful

Ol’ Faithful This geyser is one of the main attractions at Yellowstone National Park. People visit from all over to count down the seconds before it erupts.

Ol’ Faithful’s Process There is water in the cracks on the ground. This water heats up and starts to make bubbles and steam. The pressure starts to build up and eventually the water shoots up…
