Ice Ages
Illinois State Museum
EXCERPT: When most people hear the words Ice Age, they think of glaciers covering much of North America and Eurasia, animals like mammoths and saber-toothed cats, and Cro-Magnon people painting cave walls. These things come to mind because the words "Ice Age" often refer to the last time that glaciers extended over a large portion of the Earth's surface. LINK WITH FLASH CHART It is our attitude toward free thought and free expression that will determine our fate. There must be no limit on the range of temperate discussion, no limits on thought. No subject must be taboo. No censor must preside at our assemblies. –William O. Douglas, U.S. Supreme Court Justice, 1952 |
