The Hunt for Ancient Glaciers

1 2 3 4 »

Water is the most wonderful thing in the world. It is the only substance which occurs in all three states of matter, solid, liquid, and gas.... This versatile material is the most active agent on the face of the earth ... shaping the land surfaces by rain and rivers [and] ... glaciers - rivers of ice. ... The glacier, a brittle solid, has the power of motion under the pull of gravity, and is the most efficient sculptor of mountain forms and transporter of rock burden among the geological agencies.

The work of ice, and the climates that make it possible, have always had a fascination for me as a geologist; and for more than 50 years I have occupied myself more or less continuously with the study of glacial problems. This study has led me to all the continents to observe the proofs of ancient glaciation to be found even within the tropics.
