Normally, hidden spots within the state remain hidden because of their remote locations in small towns, but that’s not always the case – and the Jackson Volcano is the perfect example. Although located in the capital city, it remains one of the biggest secrets in Mississippi, with many residents completely unaware of its existence.

Located in Hinds County, Jackson is not only the state’s capital; it’s also the largest city in Mississippi.

It’s home to nearly 200,000 residents…and an extinct volcano, which is located 2,900 feet beneath the city’s surface.

Most of the volcano is located directly underneath the Mississippi Coliseum.

Although signs of the volcano may not be visible, massive amounts of carbon dioxide remain trapped beneath the coliseum, a reminder of eruptions from days long gone.

The volcano was first discovered in 1819, and in 1860, scientist E.W. Hilgard published an article on his theories and observations after studying it for himself.

Scientists estimate the volcano is about 70 million years old, with it having been extinct for approximately 66 million years.

Surprisingly enough, the Jackson Volcano isn’t the only one in Mississippi. There’s another one located underneath the small, unincorporated community of Midnight.

Aside from Jackson, there are only three other volcanoes located within city limits in the United States - Diamond Head in Honolulu, Hawaii, Mount Tabor in Portland, Oregon, and Pilot Butte in Bend, Oregon (pictured).
