It came from Outer Space.

Most of us at one time or another gazed into amazement at the night sky and watched streaks of light. On rare occasion we can hear the crackle as a “close one” burns up in the atmosphere. These are true visitors from outer space- meteors.

About twice a day, somewhere in Canada, a meteor thuds to Earth. Most are only about 100 grams in weight and make little impact; but a few have struck with a tremendous explosion, ripping apart the ground and leaving telltale circular craters or altered minerals.

To date scientists have recorded about two dozen meteor craters in Canada The 95-kilometre-wide strike in Sudbury is Canada’s largest. The impact of what must have been an enormous meteor was so broad and deep that it completely altered the mineralization of the bedrock and created Canada’s nickel deposit.

Of the five meteor craters in Ontario (Others are near Brent in Alqonquin Park, at Wanapitei Lake west of Sudbury, and at Slate Islands in Lake Superior), that at Holleford north of Kingston, is the most readily visible from the ground. It was first discovered in 1955 by a team of scientists at the Dominion Observatory in Ottawa by poring over aerial photographs. Later research concluded that extraterrestrial interloper must have arrived around 550 million years ago and measured 90 metres across, Exploding into the ground at an estimated 55, 000 kilomotres an hour, it has left a crater 2.35 kilometers in diameter and 30 metres deep.

To reach it, drive to Harrington on Highway 38, about 25 kilometers north of exit 611 on Highway 401. From the centre of the village take the Holleford Road east for about 3 kilometers  and follow the road as it bends to the north (left) Another 1.5 kilometers brings you to a T intersection, where you turn right. Then, after another 1.6 kilometers, the road descends a slope. This is the southwest wall of the crater. The road continues east along the slope of the crater for another kilometre to the Crater Farm and the one-time hamlet of Holleford, where a plaque stands by the fence on the north side of the road.

As with most meteor craters in Canada, erosion has softened its features and vegetation covers most of its slope. Yet it is hard not to stand and wonder how the ground must have shaken when this visitor from out space thundered to the Earth.
