101 American Geo-Sites You've Gotta See (geology Underfoot) [Paperback]

Rocks racing across a lakebed in Death Valley. Perfectly preserved 36-million-year-old tsetse flies in Colorado. Dinosaur trackways cemented into ancient floodplains in Connecticut. A gaping rift in the Idaho desert. What do these enigmatic geologic phenomena have in common? Besides initiating a profusion of head-scratching over the years, these sites of geologic wonder appear side by side, for the first time, in a single publication.


Examining in detail at least one amazing site for all fifty states, Albert Dickas clearly explains the geologic forces behind each one s origin in 101 Geologic Sites You ve Gotta See. Dickas discusses not only iconic landforms such as Devil s Tower in Wyoming but also locales that are often overlooked yet have fascinating stories. Consider the Reelfoot scarp in Tennessee: to the casual observer it is nothing more than a slight rise in a farm field. Yet this subtle slope represents a rift formed during an 1812 earthquake that forced the mighty Mississippi to flow upstream. Or Lousiana s unassuming, low-lying Avery Island, which actually caps an 8.5-mile-high column of salt. Amply illustrated with full-color photographs and illustrations and written in clear yet playful prose, 101 Geologic Sites You ve Gotta See will entertain and inform amateur and seasoned geology buffs whether from an armchair or in the field.
