Scuba diver captures video of 2 classic cars in the Detroit River

In the murky depths of the Detroit River,scuba diver Matt Zuidemahas seen it all: A toilet, old safes, spare tires. Even a grand piano.

Near Caron Avenue, herecently spotted a few vehicleshe hadn't seen before two classic cars, about six to 7.6metresdown,covered in zebra mussels and fishing gear.

One, he believes, is a sedan that dates back to the 1940s.The other is flipped upside down. Hesuspects it'sa late 1950s Thunderbird.

"The car people can tell me different. I'm not a car guy. But certainly those tail lights are a giveaway for something like that."

Zuidema, a scuba instructor with 25 years of experience, is one of few people who divesin the highly restricted area.

He was given animage of the vehicles that was captured by side-scan sonar, and he went down to check them out.

"We just wanted to get confirmation of exactly what they were," he said.

He recently posted his findings on YouTube.

Matt Zuidema talks about seeing two classic cars and finding other items in the Detroit River

"Every single time I dive, I find things that are new," he said.

"So because the sediment on the bottom will cover things up and then uncover it as seasons go, a lot of times I'll dive a spot a year and then a year later and I'll see things that I didn't see before, just simply because the sediment moves on the bottom of the river as well."

Harbour master Peter Berry of the Windsor Port Authority said cars are common along the Detroit River.

Standing at the foot of Mill Street with the river behind him, he said 10 vehiclesthat have been identified by Navy divers in that area.

The Detroit River has historically been a dumping ground, he said.On our side of the river, however, therehaven't been as many unusualfinds as on the American side.

Cannons dating back to the first French settlers have been discovered there, he said. There arealso many bottles dating back toprohibition.And now, firearms turn up.

"We're improving the environment, but we're still seeing things get dumped there," he said.

Any type of object found in the water has to be reported to the port authority, Berry explained. And not just anyone can scuba dive in the Detroit River, even if you're certified you have to get a permit from the Windsor Port Authority.

That's because it's dangerous. The riverhas a calm bottom with a fast-moving top level, and a middle layer that is even faster. Thiscreates a rolling undertow that can sweep away even experienced divers.

The bottomis also littered with hazardousdebris such as rebar, he said.
