Yellowstone earthquakes

Yellowstone National Park, a must-see for everybody, is best known for its geysers, but the park is really a giant volcano. Yellowstone's caldera takes up most of the land of the park.

And where there are volcanoes, there are usually earthquakes--so it should be any surprise that there have been a series of minor quakes within Yellowstone over the last few days.

Six years ago the Marathon Pundit family drove to Yellowstone, we stayed in a cabin just west of the park, in Montana, on the shores of Hebgen Lake, a reservoir of the Madison River.

A few miles upstream from Hebgen Lake is Quake Lake, which was formed after a 1959earthquake, which measured 7.3 on the Richer Scale, the strongest in recorded Montana history, triggered a landslide and created a natural resevoir.

Quake Lake, pictured in 2002, is located in the Gallatin National Forest. There's a small memorial and historic exhibit located along State Highway 287.

The earthquake caused 28 deaths, most of them campers.
