old faithful

Shaul Hurwitz

Old Faithful geyser is one of the most popular areas in Yellowstone National Park. But a major climate event nearly 800 years ago made the geyser a little less faithful. Wyoming Public Radio's Ivy Engel had a conversation with U.S. Geological Survey research geologist Shaul Hurwitz, who studied this strange period.

Old Faithful is known for being, well, faithful. But it wasn't always that way. In fact, according to new research published in Geophysical Research Letters, it once stopped erupting for nearly 100 years.
