Islands in Deep Time: Ancient Landscapes Lost and Found by Markes E. Johnson is a highly recommended guided geological journey through deep time to find the traces of ancient islands. The greater appeal of this scholarly work targets professional and academic readers working in the field or related fields. Armchair enthusiasts will appreciate the journey too, especially if you are interested in ancient islands and their discrete ecologies and well preserved fossil plants and animals.

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.
