Much is already known about those who used Lake Minnetonka before now, but there is still so much more waiting to be discovered.
"We want to make a national historic shipwreck district on Lake Minnetonka," Ann Meriman told FOX 9 News.
Meriman and her husband Christopher Olson are the founders of Maritime Heritage Minnesota. Both are licensed archeologists, and they recently completed the first survey of a Minnesota lake. Grant money helped them methodically comb the surface of Lake Minnetonka using advanced sonar and GPS equipment.
The couple found 129 so-called anomalies in the process. Each could be considered an archeological find if they turn out to be at least 50 years old. Unlike other known shipwrecks within Lake Minnetonka, these recording would be all new finds.
Once Olson and Meriman secure their next round of grant funding, they will dive at each site to take a closer look. First on their list is a seven-foot image that looks like a hot dog bun to the untrained eye, but they believe it could be a dug out canoe.
"They are extremely rare. They are such a big part of the history of the state, the Native American culture," said Meriman. "It might not be. We really don't know until we dive on it, but it really looked like it."
"It would really exciting because then we would have something from every period of history on the lake," added Olson.
They couple is the first to admit more research is needed, especially on an image they believe could be the first steam boat on the lake dating back to the 1860s. The boat had several names but was fist called the Governor Ramsey.
"We've got an anomaly that is the perfect size just off Shady Island," says Meriman. "Could be a pile of sand, but it's got a pointy end to it."
Olson and Meriman hope to dive and take a closer look at their finds sometime between now and October.
