An ice-age river has been discovered running beneath Toronto:
The existence of a bedrock valley was first documented in the first half of the century, but its exact location remained largely unknown, said Steve Holysh, a hydrogeologist working on the project…
In tests done in August, researchers at the High Park site expected to hit bedrock at about 40 feet, but it wasn't until a depth of 123 feet that they hit the river system, technically known as an artesian aquifer. They hit bedrock at 145 feet.
