A hotspot is simply a location at the earths crust where magma from the mantle releases heat and in turn shapes the crust. Yellowstone has a hotspot trail which has developed over many eruptions while the plates were in motion. The hotspot is more difficult to track than the Hawaiian Island chain but by using various dating techniques and carefully analyzing the surrounding rocks geologists have been able to identify several such hotspot eruptions over a period of approximately 17 million years.
