Hilltops surrounded by farmland in southern Wisconsin turn out to be the eroded remnants of an ancient archipelago. An island in the Yellow Sea where Korean tourists flock is the peak of a flooded mountain rising from a drowned continental shelf. From a mountaintop shrine to Genghis Khan in Inner Mongolia, the silhouette of a Silurian seascape can be spotted. On the shores of Hudson Bay, where polar bears patrol the Arctic tundra, a close look unveils what was a tropical coastline encrusted with corals nearly 450 million years ago. The geologist Markes E. Johnson invites readers on a journey through deep time to find the traces of ancient islands. He visits a dozen sites around the globe, looking above and below today's waterlines to uncover how landscapes of the past are preserved in the present. Going back 500 million years to the Cambrian through the Pleistocene 125,000 years ago, this book reconstructs how "paleoislands" appeared under different climatic conditions and environmental constraints. Finding vestiges of prehistoric ecologies, Johnson emphasizes the complexity of island ecosystems and the importance of preserving these significant sites. Inviting and accessible, this book is a travelogue that takes readers through time as well as space. Islands in Deep Time shares the adventure of exploring striking locations across geologic eras and issues a passionate call for their conservation. No library descriptions found. |

This is a journey through deep time across the geography of today's world in relationship to the origin of paleoislands. Each chapter includes a topographic map and a global map showing the location. These maps trace the changing positions of continents and oceans beginning five hundred million years ago to the present. There are many photos throughout.
Chapters focus on: New Hampshire's Mount Monadnock, Wisconsin's Baraboo Archipelago, Hudson Bay's Jens Munk Archipelago,Inner Mongolia's Bater Island, Western Australia's Mowanbini Archipelago, Western Australia's Labyrinth Karst, Wales St. David's Archipelago, Baja California's Erendira Islands, Maderia Archipelago, Azorean Santa Maria Island, Islands on the African and Pacific Tectonic Plates, and descending Mount Misen on Japan's Miyajima.
Johnson helpfully includes a Glossary for those of us who are a bit rusty on our terms. This is followed by the Notes, Bibliography, and index. This book is a travelogue that takes readers through time showing how ancient island seascapes can be viewed today from the rock record.
