While Strahler leaves no doubt over his view of Christian creationists, he provides such a wealth of their material that the book might well be considered "balanced". It is certainly thorough in presenting a history of modern creationism and its spokesmen [if there are any women active in promoting "creation science" they don't appear here]. Strahler lays a foundation by comparing science and pseudo-science. The contrast between empirical research and declaration from assertion should be apparent to all, but Strahler spells it out carefully and clearly. From this beginning he takes us through a succession of topics, exhibiting the creationist declarations, then depicting the errors in them. In some cases, the errors are simply false, while others are twisted use of words or ideas. Strahler set himself a monumental task in composing this book, but as someone with long experience in the geologic column, perhaps there is no-one better qualified to assess the material.

This is a rich trove for almost anyone interested in the planet's history. Most of the line drawings and other illustrations are worthy of close attention. Although set as a counter to false thinking, there is a massive amount of material on such topics as radiometric dating, cosmology, geological processes, fossil analysis and the evolution of humanity. Each area acknowledges the leaders in the research. While crediting good studies, Strahler is careful to note where his fellow scientists have been slipshod or dismissive over word usage in dealing with creationists or simply reporting their science. A worthwhile book for a wide spectrum of readers. [stephen a. haines - Ottawa, Canada]

It is true that Strahler (p. 135) falsely blames creationist John Woodmorappe of misrepresenting the contents of an article on the radiometric dating of some Hawaiian basalts. In reality, the distortions originated from creationist H. Morris. Nevertheless, Strahler's rebuttal of the distortions is valid.

Clearly, Strahler needs to update this book and respond to the blatant misquotes, misconceptions, and errors that permeate the tabloid literature that continuously streams from various creation "institutes" that claim to be doing "research" or have "answers." For example, geologists have known since at least the early 1960's that SOME magmas travel rapidly through crusts, as fast as several ten's of kilometers per month. Since the first printing of Strahler's book, creationists have distorted the literature on magma movement and cooling, including some of the references in Strahler. Creationists illogically imply that because SOME magmas travel quickly and smaller plutons may cool rapidly, ALL magmas must travel and cool quickly. As a specific example, Strahler needs to supplement his discussions on p. 212-213 and further describe how the cooling of huge plutons, such as the Sierra Nevada Batholith of California (p. 213), took more than 10 million years and how this and other numerous plutons thoroughly refute creationist claims that the Earth is only 6,000 to 10,000 years old. Strahler should also discuss the 1989 Science article by Odom and Rink that destroys creationist claims for "ex nihilo" polonium halos.
