About this sheet
The physical structure of South America, "The Mountains, Table Lands, Plains & Valleys of South America" by Alexander Keith Johnston, F.R.S.E., published in 1852 by William Blackwood & Sons, Edinburgh and London, as a plate of Johnston's Physical Atlas of Natural Phenomena. The plate is numbered 9 in the margin and headed "Geology."
The map shows the continent without political borders. The Andes run down the Pacific side in a long chain of brown shading, with the high plateaus and valleys of Peru and Bolivia drawn between their branches, while the Brazilian highlands rise in tan on the Atlantic side. The great basins of the Amazon, the Orinoco and the Rio de la Plata are tinted green and crossed by blue rivers. At the lower right an inset gives "Section of S. America from the Pacific to the Atlantic Ocean," a profile showing the heights of the Andes and the lower ground east of them, set above the title.
The plate belongs to a series in which the physical form of each continent is shown in the same manner, and it is notable for putting the Andes at the center of its picture.
