Note 21 — Chapter III · ON THE PLAINS AND VALLEYS OF CHILE:—SALIFEROUS SUPERFICIAL DEPOSITS.
Reading edition
According to Azara (“Travels,” vol. i, p. 56) there are salt-lakes as far north as Chaco (lat. 25°), on the banks of the Vermejo. The salt-lakes of Siberia appear (Pallas’s “Travels,” English Trans., vol. i, p. 284) to occur in very similar depressions to those of Patagonia.
