New tests confirm Lake Minnetonka canoe is 1,000 years old
Star Tribune ^ | April 11, 2014 | Kelly Smith

Posted on 04/11/2014 9:38:33 AM PDT by SunkenCiv

The canoe, made from a hollowed tree trunk by some of the earliest American Indians to live on the lake and in the state, was initially dated to about 1750. But recent radiocarbon testing now dates it to between 1025 and 1165 — making it one of the oldest watercraft finds in the state...

The canoe was discovered in 1934 as a family was building a dock on the shore of Lake Minnetonka’s North Arm in Orono. Severe drought had dropped the lake below normal water levels, and one of the dock posts hit what family members thought was a log. They unearthed it and discovered it was the well-preserved dugout canoe, long embedded in the lake’s silt and mud.

The canoe has bounced around to different museums and been lent to various groups.

When no one else had space — or, perhaps, interest — the Western Hennepin County Pioneer Association took it in 1961, adding it to the dozens of family heirlooms and antiques that people have discarded, such as tea cups, a war flag, even a moose shot by Theodore Roosevelt that another museum didn’t want...

Last year, St. Paul nautical archaeologists Ann Merriman and Chris Olson came across it. Intrigued, they set out to study it and seven other dugout canoes in Minnesota...

With a $9,000 state grant, the couple researched and did radiocarbon analysis on the canoes found across the state, from the Minnesota River in Bloomington to Dutch Lake in northern Minnesota.

The study, released Tuesday by Maritime Heritage Minnesota, determined that the Lake Minnetonka canoe, which is 11 feet by nearly 1.5 feet, is the oldest. It’s also in good condition despite some deterioration since it was unearthed; it’s lost small pieces and a large crack splits it.

So how can they be sure it wasn't built by a viking? After all, they made it as far west as Alexandria to leave a Rhunestone.

Model and Serial Number. Usually a metal plate is mounted on the stern.

Silly.

“Western Hennepin County Pioneer Association took it in 1961”

Took it, Just took it. I sure hope the guy that left it there doesn't need it again.
Head shaking.

It doesn’t look seaworthy. Did the Marxist fascists therefore legislate 22,374 new government regulations for canoes?

“It doesn’t look seaworthy.”

Perhaps that is why it was at the bottom of a lake.

So it was purified in the waters of Lake Minnetonka?

Wouldn’t the test show how old the tree was from which the canoe was carved, not when the carving was done? Or am I missing something?

The Minnesota Department of Natural Resources determined an additional 700 years of boat fees was due.

Did they find my guns by it? I am pretty sure this was the same area of my tragic boating accident...

Right, the RC dating shows the oldest possible date, which is the youngest ring; if the bark is present (possible, but unlikely), the date of the cutting can be found. But this is a hollowed out log; the only missing layer is likely to be the last one, so, they know when it was cut. :’)

So the carbon dating varies from sections of the tree, from inner to outer, to the bark, is that correct?

It’s called radiocarbon dendrochronology. Dendrochronology as a technique began before radiocarbon dating, but only yielded relative dates, and they were (as you might imagine) a little subjective. The technique began in the SW US where there are timbers in precolumbian structures that can have their ring spans counted (for the age) and measured (for comparison with other samples of the same species).

Radiocarbon dating used to use a lot more of the sample, so it was used sparingly; as technology improved, IOW, by about 1970, it was possible to get a more accurate date with much smaller samples, making radiocarbon dating of each ring practical. Before this, a log might be cross-sectioned, and the slice dated, yielding an average date, which works adequately because the rings could be counted beforehand.

Dating individual rings turned up the infomrmation that the RC quantity in the atmosphere varies from year to year; that in turn made dendrochronology more important, since the sequence of fluctuating values can be “wiggle-matched” to build a ring sequence beginning with living specimens, and going back to overlapping sequences in dead samples, then overlapping those with older samples, to build a continuous sequence that can be cross-checked by other labs using second samples from the same specimens.

Nah, your guns and your canoe were seized by the Bureau of Firewater, Canoes, and Thundersticks.

Wow, even I felt a little offended by that one.

Generally people build things out of freshly cut wood. They might have even taken advantage of a fallen log that was one or two years old, but after that the logs tend to rot. So the reasonable assumption is that this was carved within a short time frame of when the tree died.

That much I understood but where I was uncertain was getting different carbon dates for different parts of the tree. I assumed the item would give one date overall. I’m still not sure if I’m right about that but if so then it makes sense.

Ahhhh... well in that case the younger date could have come from fungus or spores that may have grown on the old log if it became partially exposed at some point or an air pocket became trapped under it. The growth would have died away a long time ago but left biological material causing C-14 ratio-contamination between cracks in the much older log — that’s just one example.

You can’t bow fish for carp in Lake Minnetonka because it is a designated muskie Lake.

So, the northern Native Americans’ technological high-water mark was reached about 1,000 years ago...since then even their latest advance, the casino, has only been an adaptation of a European invention.

Expired registration sticker, ID numbers not visible from both sides, and no invasive weeds sticker at all. Authorities are searching for the rightful owners to discuss fines.
