Dust Cloud

Near the end of the 1960’s, no water was left in Lake Texcoco, down to its very last nook and cranny and for most part of the year. During rainy seasons, its basin would fill, emptying itself over the city, flooding its main streets, although this would only occur for a couple of months. The remaining part of the year the earth, waterless, would dry out, its grains of dust and salt left exposed to the sun and the wind. This wind would lift the thicker grains and would drag them, making them roll at ground level, leaving the lower layers of the earth exposed and bare. With its force in every direction, the wind would lift the dust upward to then thrust it suddenly to the ground, fracturing the soil in localized explosions of aeolic erosion. When thicker particles would fall on the ground, finer ones would then rise in huge screens of dust that, as they accumulated, would form “walls” of sorts. The volatile particles of these “walls” would rise even higher in the shape of clouds, manipulated by the more subtle currents, and, at very high speeds, directed back towards Mexico City. [...]
