How did a boulder over a billion years old wind up on Toronto's Bloor Street?
from CBC News
At first glance, it might look like it came from outer space, but experts say a giant rock dug up during the construction of a downtown Toronto parkette originated right here on Earth, where it's believed to date back over a billion years. The 2,000-kilogram granite boulder turned up during the digging for a parkette in the Bloor-Annex business improvement area — and is estimated to be 1.1 billion to 1.4 billion years old. "It gives us a link to the past," said Brian Burchell, chair of the BIA.
