Milton, OntarioMilton Quarry, operated by Dufferin Aggregates in Milton, Ontario This is Canada's largest working aggregate quarry. A school tour by the FabFours of a working quarry:
|
|
 The first part of the tour is a guided
tour on the school bus. A person from Dufferin Aggregates acted as our tour
guide. |
|
| On the tour we saw how the rocks were extracted. The wheels on these dump trucks are taller than an adult! |
  |
||
  |
|||
| When the rocks are brought to the primary crusher, they are then processed. How small the rocks get crushed depends on what will be made with the aggregate. |
  |
||
| After the rock is crushed, it is sorted into different sizes. Trucks load up and drive to construction sites where the aggregate is used. |
  |
||
 |
  |
||
| When the quarry has used up all of the rock that it can in one area, it rehabilitates the land by turning it into a natural habitat for wildlife and recreational spaces for people. It takes years for nature to take back the landscape - but it does! |
  |
 |
|
| The quarry is reclaiming the used land by converting it into a wetland. You can actually see this part of the quarry from the Bruce Trail. |
  |
||
| At the end of the tour, we got to get off the bus and look for fossils in the limestone gravel Students may only get off the bus outside of the quarry's gates. |
  |
||
| These are some of the fossils that can be found in the limestone. The quarry makes gravel & sand from the limestone. |
