According to the article, these stacks were used as navigational landmarks. It's amazing in the GPS age that it still is easier to line your boat up on a landmark.

There is a project out for bid here that boaters have been using as a navigational landmark for years. I think it would be fun to shoot it just before sunset. There would be dozens of lost boaters .

Here is some facts and the dmolition plan on the "Sisters". Date is June 12th

The Stacks - The Four Sisters:

Each stack is 146 metre tall (493 feet)
Base Diameter - 12.2 metres (40 feet)
Top Diameter - 7.3 metres (24 feet)
Reinforced Concrete lined with brick
Each stack 1,583 cu. yd. of brick
Each stack 2,136 cu. yd. of concrete

The Demolition:
Contract with Murray Demolition - Toronto

180 degree arc is exploded out of the east side of the stack to create a void causing the stack to fall in an eastern direction

Stacks will fall like trees at approximately eight (8) second intervals

They will fall to the east with the easterly most stacks falling first

Each stack has a smaller ash silo adjacent that will also be demolished

Sequence will be most easterly ash silo followed four seconds later

By the most easterly stack, then four (4) seconds later the next silo, four (4) more seconds the next stack until they are all down.

RDZ,

I don't know. I do know that Murray Demolition out of Toronto is the main demolition contractor. I have been in a call to them and left a message. As soon as I hear back form them I will let you know.
