The Rise and Fall of San Diego - 150 Million Years of History Recorded in Sedimentary Rocks Butterflies Excellent descriptions and glossaryRise and Fall of San Diego tells the prehistory of the San Diego area as recorded in the layers of sedimentary rocks. The land here has risen and fallen independently from the sea level which also has risen and fallen. The ever changing landscapes and animal life through time are examined in this book. Numerous field trips direct the reader to key localities to observe and understand the history stored in the rocks. Patrick L. Abbott, 1999, 231 pages,
