When we last heard from the Rediscover North America canoe expedition, they were in New Ulm, Minnesota on their 5,200-mile journey from the Gulf of Mexico to the Arctic Ocean. Now, after puncturing a canoe on a piece of rebar and struggling across a series of unusually low rivers and streams, they’re just south of Grand Forks, North Dakota, 150 miles from the Canadian border.

The Upper Minnesota River proved especially troublesome. Expedition member Luke Kimmes reports, “We had some information that the Upper Minnesota was going to be low water, muddy, and lots of log jams. All of that turned out to be true. The water definitely disappeared, the mud came in, and the log jams were there.”

When the six-man team finally reached the Red River, they came across the first rapid of the expedition and downstream current, a welcome relief after paddling up the Mississippi.
