Études sur les glaciers

The revolutionary glacial theory, proposed in this work of 1840, contributed to the demise of the myth of the great biblical flood.

Louis Agassiz (1807–73), one of the foremost scientists of his day, took up the study of glacial geomorphology in Switzerland in 1836. When he published his revolutionary glacial theory in this work of 1840, he greatly undermined the hypothesis that landscape features were the result of a great biblical flood.Swiss-born zoologist, geologist and paleontologist Louis Agassiz (1807–73) was among the foremost scientists of his day. When he took up the study of glaciology and glacial geomorphology in Switzerland in 1836, he recorded evidence left by former glaciers, such as glacial erratics, drumlins and rock scouring and scratching. In this work, published in 1840, he proposed a revolutionary ice-age theory, according to which, glaciers are the remaining portions of sheets of ice which once covered the earth. His radical suggestion undermined the hypothesis that landscape features were the result of a great biblical flood. Although Agassiz's invaluable work led some to acclaim him as the 'father' of glacial theory, critics have cited the contributions of others, including Jean de Charpentier and Karl Schimper. The book also describes the features of active glaciers, including ice tables, ice pinnacles and moraines.
