JOPLIN, Mo. – You can catch some beautiful sights at this year’s Rock-A-Thon in Joplin, Missouri.

The Joplin Historical and Mineral Museum is hosting its 22nd Annual Gen and Mineral Expo. You can find dealers, bead jewelry, learn about identifying local minerals, check out a rock swap and more. You can get into the Rock-A-Thon event for free. Also, organizers are giving away door prizes.

The Joplin Historical Museum is located at 504 S Schifferdecker Avenue in Joplin. Its collections tell the story of Joplin and the Tri-State Mining District. The museum includes two distinctly different museums: The Everett J. Ritchie Tri-State Mineral Museum and the Dorothea B. Hoover Historical Museum.

“The Everett J. Ritchie Tri-State Mineral Museum is teeming with incredible specimens from local geological finds. Upstairs there is a fully functioning miniature-sized model of a mine inside and out,” states the museum’s website. Each one takes a different path through history, but ultimately reveals Joplin’s rich past through different aspects.

According to the museum’s website, its mineral collection is “one of the world’s most exceptional collections of  lead and zinc ores as well as other minerals found in the Tri-State District.” You can learn about the geology and geochemistry of the area. The Mineral Museum also demonstrates the mining process and methods used from the 1870s through the 1960s.

Marvin Dahmen, a vendor at the Rock-A-Thon event tells KOAM, “There’s no reason why a person would become interested in rocks. Some people collect knives, some people collect stamps and coins. I’ve always enjoyed rocks from the time I was just a little kid. It’s just something that is sort of inborn. I didn’t choose it, it chose me.”

Dahmen adds, “When I was five years old, every rock was a good rock, because I knew nothing about rocks.”
