GUID (UUID V4):

Sea cliffs with excellent zeolites in basalts. Cape Grim is located on the far northwestern point of Tasmania. Cape Grim is part of the Van Demons Land farm. It is accessed by travelling through one of Tasmania's largest dairy farms. The collecting spot is now difficult to access as the installation of wind turbines has restricted public access - just another blow to self collecting.
