Bay of Biscay Country
Named after the Bay of Biscay which is notorious for its rough seas and violent storms, “Bay of Biscay country” describes the dangerous and uneven ground which can be present in certain areas.
“Crab-holes” can be found on the surface which were often the cause of serious accidents. They can occur on the basaltic plains and are generally due to the unequal decomposition of the underlying rock.
Bay of Biscay Country is marked on the Moolort Plains near Carisbrook on this 1860 map of the Castlemaine Mining District.
