Where to find serpentine substrate?

[Smitty]

Been scouring the web for a little serpentine substrate to experiment with. Anyone have any suggestions on where I may obtain some?

Be difficult because it is often associated with asbestos. I think there is a serpentine based fertilizer in Australia. Check Richard Davion's videos.

Otherwise get you shovel out (map of serpentine and ultramafic soils in the US):

This was my next plan of attack when I head out for my motorcycle trip next weekend.

Thank you Sir!
