The book is written for general audiences, with clear definitions of terminology that is familiar to most geoscientists. Even so, I was pretty grateful for it when I was switching from physics to geophysics and didn’t yet know that a bajadas was an alluvial fan as a river spills out and deposits in a desert instead of a delta at a lake or ocean. The glossary perfect people without a geology background reading the book out-of-order, or needing a reminder, and will be totally overlooked by geoscientists.
Now, a few years past my proto-geoscientist stage, I still love the book for using the terms properly once they’re defined, and for providing a thorough geologic history for an area totally unfamiliar to me with my heavy emphasis on western Canadian fieldwork. The page of additional reading and references, and the full-spread geologic map including major structures is ideal for self-guided explorations.
This book contains the clearest, most beautifully illustrated examples of arid weathering (exfoliation, honecombs, ventifacts) that I’ve encountered, with lots of tips on where in the park to roam to see examples with my own eyes. It also includes a few pieces on the interaction of people with their environment, suggesting some more anthropology-centric stops of cave painting and historical structures to keep my less rock-obsessed companions cheerful.
Barker Dam reservoir is part of the Wonderland of Rocks, a site of a much shorter exfoliation dome than the more famous Half Dome at Yosemite National Park.
