No. 19

[Pencil section with ink additions showing "a singular kind of tilt" of two low ridges with identical succession of strata, Copiapo, included a purple bed 'A', but dislocated by a fault comparable to that shown on 610. Darwin surmised that since the two ridges are joined at the head of the valley they must have been twisted through 135 degrees, like twisting a piece of paper. 'R M 1831 1', 20x15cm. Based on the pencil sketch in the Despoblado notebook,p. 8b and described in South America,pp. 231-2.]
