Hot Spot Theories

Two Hotspot Theories

MOLTEN ROCK, or magma, rises in convection cells, like water boiling in a pot. The left side of this illustration shows the traditional view of a hotspot as a plume of magma rising from the earth's core. The right side shows another theory that the Yellowstone hotspot originates at a much shallower depth.

Fishing Bridge.  

Did You Know?
You cannot fish from Fishing Bridge. Until 1973 this was a very popular fishing location since the bridge crossed the Yellowstone River above a cutthroat trout spawning area. It is now a popular place to observe fish.
