Wind Swimming Sierra Negra's Upside Down Country

‘Upside down country’ is an Australian Aboriginal term for country that has been mined, turned upside down. It is a metaphor for mans activity, turning land ‘upside down’ for his own resource, either for mining or habitation or exploration. I often wonder how the broken, rearranged landscape formations of mans activities must look to the wild migratory birds as they fly on their annual travel routes. These birds often follow rivers and use the imprinted knowledge of land formations for direction.  As whole mountains can be moved overnight the implications are that other species will become confused or rerouted and unable to depend on familiar landmarks to read the land. (Just as whales and dolphins are being confused, unable to hear or read the natural signals below the oceans by interference of sonic radar from shipping).
