A unique deposit of quartzitic schist in the Mojave Desert of Southern California is quarried by Sydney Peak Stone.
First it's gathered and stacked this way.
At Sydney Peak Qarry
Then it's stacked this way on pallets and shipped to Gualala
Then it's 'trial stacked' dry laid this way, before it's lime mortared.
To see how it fits around the trunk of the tower.
Then its stacked and wet laid this way in a special hot lime mortar
To make a permanent masonry structure
And after cutting it up and shaping of a lot more of it.
Many tons of it is dry stacked again in a preliminary cone shape in preparation for the roof assembly
And then dry stacked once more !
To create the tower roof - all dry laid !
