VSF-ish

The family went to a 2nd Birthday party at a park across town today.
The park itself was once used as the facility to store coral that had been dredged from Moreton Bay before it was crushed up and turned into concrete.
They have one of the old crushers there and I took this pic.

The way that it's buried into the ground made me think of some sort of Victorian Sci-Fi tunneling machine.

It was a massive piece of machinery.
Here's a closer shot along the shaft.
