Siberia, like Patagonia, appears to have been recently elevated above the waters of the sea. In both countries the salt-lakes occupy shallow depressions in the plains; in both the mud on the borders is black and fetid; beneath the crust of common salt, sulphate of soda or of magnesium occurs, imperfectly crystallized; and in both, the muddy sand is mixed with lentils of gypsum. New Philos.
We could not reach the pointed hill by night. The country is now more densely scrubby than ever, and although we toiled the whole day, we only made good twenty-four miles. Upon nearing the hill the following morning we saw some grass-trees and passed between two salt-lakes. At ten miles Mr.
These ranges, such as they are, occur at intervals of a few miles up to thirty or more, and between them scrub-covered plains, sand-plains, or flat stretches of open forest are found. In the deeper undulations, long chains of dry salt-lakes and samphire-flats are met with, occupying a narrow belt, perhaps one hundred miles in length.
Darwin says, that with other small Rodents, numbers live together in nearly desert places, as long as there are a few blades of vegetation left; and that they swarm on the borders of salt-lakes, where not a drop of fresh water can be procured. Some of them lay up stores of food, especially those which inhabit northern countries.
Salinas, or natural salt-lakes, occur in various formations on the eastern side of the continent, in the argillaceo-calcareous deposit of the Pampas, in the sandstone of the Rio Negro, where they are very numerous, in the pumiceous and other beds of the Patagonian tertiary formation, and in small primary districts in the midst of this latter formation.
In both countries the salt-lakes occupy shallow depressions in the plains; in both the mud on the borders is black and fetid; beneath the crust of common salt, sulphate of soda or of magnesia occurs, imperfectly crystallised; and in both, the muddy sand is mixed with lentils of gypsum.
Westward, through the boundless steppes, whither or why we knew not; but that the All-Father had sent us forth. And behind us the rosy snow-peaks died into ghastly grey, lower and lower as every evening came; and before us the plains spread infinite, with gleaming salt-lakes, and ever fresh tribes of gaudy flowers.
