Unsatisfied with the local stones, Toronto city planners had the
Yorkville Rock broken apart so that it could be relocated to the middle
of an urban park.
Approximately one billion years old, "The Rock" weighs 650 tons and
represents the roots of an ancient mountain range that has long since
eroded. The rock was removed in pieces from the Canadian glacial shield
and transported in huge fragments on 20 flatbed trailers to Toronto's
Yorkville Park. As each rock section arrived, it was reassembled to
minimize visible joints, although gaps remain which give the stone the
look of a tectonic puzzle.
