If you want to find out what the climate was like ages ago, one way is to grab a flashlight and head for a cave. Stalagmites, stalactites, and other mineral deposits known as speleothems contain chemical and mineralogical clues to past rainfall and temperatures. This Atlas of Speleothem Microfabrics brims with dozens of images of the formations under a microscope (called “microfabrics”). Created by L. Bruce Railsback of the University of Georgia, Athens, as a reference, the site also includes a glossary and bibliography.
