“Snowball Earth” at Fort Valley Library Lyceum

The Fort Valley Library is pleased to announce our May Lyceum presentation. Our speaker is Callan Bentley, Assistant Professor of Geology at Northern Virginia Community College.

Prof. Bentley’s talk is entitled “Snowball Earth”.  During a massive planetary ice age that occurred 700 million years ago, ice stretched from Earth’s poles to the equator and the resulting climate change switched the planet from domination by microbial slime to an oxygenated place with the very first animal fossils. Three sites in Virginia record this extraordinary tropical-latitude glaciation, which was only ended when volcanic activity induced global warming. As Prof. Bentley will explain, it’s a big story, a true scientific controversy, and a compelling brain-stretcher of a tale that will make us think about connections between climate, plate tectonics, weathering of rock, animal evolution, and ocean circulation.

Please join us on Saturday, Mayy 25th, at the Fort Valley Library and Community Center, 6190 Woodstock Tower Road, Fort Valley, VA 22652 (540-933-6714).
