On a Warm November DayPosted: November 13, 2012
This past Sunday, Remembrance Day, was an unseasonably warm day of 18 degrees Celsius in Toronto–a record breaker. To take advantage of the warmth, in the afternoon we went to The Evergreen Brick Works. We walked along the railroad tracks, past milkweed and thistles and a disheartening array of tires dumped there.
At the Brick Works, we found that many people had the same idea as us and were strolling around the grounds and enjoying the day. The colours are now soft—mostly muted browns, beiges, yellows and greens.
At the North Slope of this once quarry was a Toronto Parks and Recreation sign noting the geology of the slope that reveals evidence of several ages of ice alternating with warm periods. The sign reads as follows:
-The North Slope is a geological feature of international significance.
-Professor A. P. Coleman, a world-renowned Toronto geologist, first identified the significance of this slope in 1894.
-This site was one of the first in the world to reveal a rare sequence of climate change. The deposits here indicate a glacial episode, followed by a period of climate slightly warmer than today’s, followed by another glacial episode, and lastly the climate of today.
There’s also a drawing on the sign indicating the age of the deposits that make up the North Slope. These range from the bedrock which is 448 million years old, to deposits over 135,000 years old and lastly to the most recent ones in the top layer which accumulated 13,000 – 50,000 years ago. I like to contemplate life from this other perspective—it certainly helps with a feeling a humility.
