Synopsis: Tennessee, extending 500 diagonal miles between Bristol and Memphis, cuts across numerous rock types ranging from the deformed gneiss of the Blue Ridge along the North Carolina border to the young sediments exposed in the Chickasaw Bluffs that rise 100 feet above the Mississippi River floodplain.

The state's more than 1 billion years of geologic history includes continental collisions that built enormous mountains and rifting forces that almost split the ancient continent apart. The geologic processes are still at work in Tennessee, with sinkholes claiming land in areas of limestone, rivers eroding sediment and shifting channels, and some of North America's largest earthquakes occurring every 500 years on the ancient rift faults near Reelfoot Lake.

"Roadside Geology of Tennessee" by Marcy B. Davis includes the unusual meteor impact sites on the Highland Rim of Middle Tennessee, the world-famous fossils in the Coon Creek Formation, and the source of saltpeter used for gunpowder in the Civil War. An extensive section on Great Smoky Mountains National Park includes guides to nine roads, some extending in to North Carolina.

With "Roadside Geology of Tennessee" as a guide, anyone can now explore the geologic significance of many of the state's natural and historic sties such as Cumberland Gap National Historic Park, Harpeth River State Park, Dunbar Cave State Natural Area, and Chickamauga and Chattanooga National Military Park.

Critique: As impressively informed as it is accessibly organized and presented, "Roadside Geology of Tennessee" is unreservedly recommended for personal, professional, community, college, and university library American Geology collections and supplemental curriculum studies reading lists.

Editorial Note: Marcy B. Davis earned an MS in geology at the University of Texas in Austin in 2001. She currently works as a research scientist associate at the University of Texas Institute for Geophysics, supporting field science teams working in such far-flung regions of the world as Antarctica, Greenland, New Zealand, the Arctic and Caribbean Oceans, and the western and southern United States. Marcy is also a prolific science writer with contributions to Polar Field Resources Field Notes as well as to the Earth and Sky radio series. While researching her family history, Marcy traveled the back roads of Tennessee and became fascinated with the state's geology.
