They are made with a slate/schist material trucked in from Jordon River on Vancouver Island
The stone was provided by Van Isle Slate and cost around 200 a ton delivered.
Christopher recounted that it was nice stone to work with saying it stacked very well. For Victoria standards it was a reasonable price too.Christopher took a before shot of the railway tie terracing that was originally there and then did a design in Sketchup to give an idea of what the dry stacked walls were going to look like. The final lower pic provides a good comparison shot with what was there before and the design that was proposed.
