Agatized Rainbows: A Story of the Petrified Forest Produced by Stephen Hutcheson, Dave Morgan and the Online Distributed Proofreading Team at http://www.pgdp.net "Agatized Rainbows: A Story of the Petrified Forest" by Harold J. Brodrick is a scientific publication written in the early 1950s. The book provides an in-depth exploration of the Petrified Forest National Monument in northeastern Arizona, emphasizing the geological processes that led to the formation of petrified wood and the historical context surrounding its preservation. Likely intended as both an educational resource and a guide for visitors, the book discusses the beauty and significance of the petrified wood while advocating for its conservation. In this comprehensive account, Brodrick delves into the geological history of the Petrified Forest, describing how ancient trees became petrified during the Triassic period due to volcanic activity and sedimentary processes. The narrative explains the ways in which these trees were transported, buried, and transformed into colorful stone over millions of years. Alongside the geological features, the book also touches upon the interactions of early human inhabitants with the land, such as the use of petrified wood for construction and tools by pre-Columbian Native Americans. Additionally, Brodrick highlights the importance of protecting this natural wonder for future generations while sharing the experience and fascination that visiting this unique environment can offer.
