Iowa'S Geological Past: Three Billion Years Of Change (Bur Oak Book)
“Anderson has prepared a well-written, balanced, nicely illustrated, and  up-to-date book on Iowa geology. Organization is chronological through  about three billion years of geologic time, starting in the Precambrian  when the area was vastly different from today, continuing into the  Paleozoic and Mesozoic when shallow seas were dominant leaving a rich  fossil record, and finally into the Cenozoic climaxed by the great  glacial advances. Numerous clear and simple photographs, maps, cross  sections, stratigraphic sections, landscape sketches, and especially  skillful drawings of fossils in their ancient environments enrich the  book. Coal, limestone, gypsum, sand and gravel, clay, and ground water  resources are described in summary, but substantially. An excellent  bibliography of more than 500 references is included. This incomparable  book is a masterful synthesis of geological knowledge scattered through  numerous publications that begin in the early days of exploration in the  central and western US. It will have wide appeal not only to  professional geologists but to the interested public, engineers, and  developers. and high school and college teachers.”—Choice“The only authoritative overview of Iowa's geologic record. Anderson is  to be commended for integrating the latest geological literature into  his text. His coverage is so current, comprehensive, and authoritative  that professionals as well as rock and fossil enthusiasts will each need  a copy.”—Brian F. Glenister, A. K.
