Geography and Climate
The province is located almost completely in the flat lands of the Gran Chaco, with some depressions. In these depressions lagoons have formed, mainly at Bañado de Figueroa, Bañado de Añatuya, and those near the basin of the Salado and Dulce Rivers. The Sumampa and Ambargasta sierras are the result of the influence of the Pampas at the southwest.
The soil, rich in lime and salt, is arid and characterised by semi-deserts and steppes. The predominant weather is sub-tropical with a dry season and high temperatures during the entire year; the annual average is 21.5°C, increased to 24°C in the latest years, with maxima of up to 50°C, with visible increases in temperature since 1970. Surprisingly, the maximum was of 38°C before 1910; and minima of -5°C, which has increased to -2°C. The dry season, during the winter, receives an average of 120 mm of precipitation, but the annual average is 700 mm.

Famous quotes containing the words geography and, geography and/or climate:
“At present cats have more purchasing power and influence than the poor of this planet. Accidents of geography and colonial history should no longer determine who gets the fish.”
—Derek Wall (b. 1965)
“Ktaadn, near which we were to pass the next day, is said to mean “Highest Land.” So much geography is there in their names.”
—Henry David Thoreau (1817–1862)
“The question of place and climate is most closely related to the question of nutrition. Nobody is free to live everywhere; and whoever has to solve great problems that challenge all his strength actually has a very restricted choice in this matter. The influence of climate on our metabolism, its retardation, its acceleration, goes so far that a mistaken choice of place and climate can not only estrange a man from his task but can actually keep it from him: he never gets to see it.”
—Friedrich Nietzsche (1844–1900)
