THIS ROCK MADE A BIG SPLASH.

The big boulder was nearly three kilometres wide.

It was zipping along at 75,000 kilometres per hour when it slammed into Lake Superior near Terrace Basy.

Terrace Bay survived just fine because this happened 450 million years ago

The bottom of the lake rebounded from the impact of the meteorite and created what we know today as Slate Islands Provincial Park.

This 34-acre wilderness park is an archipelago composed of a dozen small islands.

It sits 10 kilometres off Terrace Bay, and you must get out there by yourself. There are no staff, no facilities, no electricity and no wolves.

As a result of no wolve, this provincial park is home to Ontario’s largest herd of woodland caribou.

Some campers on the island - ?many of whom get there by kayak - say the caribou are so fearless they’ll eat grass right out of your hand.

The herd grew to 600 animals, until one rare winter, Lake Superior was covered with ice. That let wolf packs on the mainland discover the island and the feast waiting out there for them. They trimmed the herd to 100 animals, which naturalists say is a good thing as there wasn’t enough foliage on the islands to feed that many.

And the other rare species you may encounter on Slate Island Provincial Park is geologists from around the world

Scientists are attracted by the island’s unique rocks that are a blend of space rocks and earth rocks that collided and melted together.

Slate Islands Provincial Park is also home to the world’s largest shatter cone.

A shatter cone occurs anytime there is a collision – even a nuclear explosion.

When a drip of coffee falls off your spoon and plunks back into your coffee cup – that little splash you see popping up is also a shatter cone.

There’s a shatter cone in the park that is more than 30 feet high. It’s the largest in the world and remains the subject of debate among geologists. Is it one shatter cone or a combination of several shatter cones. There are many other smaller shatter cones in the park, usually about 1.5 metres high.

It’s pitch black at night out in Slate Islands Provincial Park. It was the perfect place to be on Sunday, August 11. That's the height of the earth’s annual passage through the Pereids - the rain storm of meteorites and shooting stars in the night sky.

Some of the ?shooting stars are travelling at 122,000 kilometres per hour.Auperior near rtres
