The Calle Tierra del Fuego of Lowry's novel (so named to reflect Cape Horn and the scorpion theme of betrayal) is in Cuernavaca the Calle de las Casas, named for the early missionary, Bartolomé de las Casas, famous for his charity to the Indians. It leads from the centre of town, south of the Cortés Palace up to the Calle Humboldt (in the novel, the Calle Nicaragua). This photograph, c. 1925, is taken from near the Calle Humboldt, looking down the steep road towards the Calle Hidalgo on the other side, which lead up to the Cathedral and towards the Borda Gardens and Teatro Morelos. From Sergio Barrera, Crónicas de Cuernavaca, 79.
