Summary

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.
