Just after last year s autumnal equinox I started an 80 or so mile backpacking trip down in King Canyon National Park, in the southern Sierra Nevadas.I m sure people that don t hike or backpack wonder what one does on such a trip besides strain and sweat and get tired and dirty Well, one of the things I do is study the world around me The high Sierras exposes a lot of geology that becomes quite fascinating once one starts looking closely, asking questions, and learning a bit For example, the famous domes of Yosemite aren t replicated in too many places why Well, it has to do with the kind of rock they re made of, which depends on where and how that rock was formed, how quickly it cooled, etc.I ve spent plenty of time in Yosemite, but that last trip was a few hundred miles south, and I soon realized the geology was different in some intriguing ways The rock around me had a lot variation in color than I usually see in Yosemite, with green and beige as well as a wide range of grays And quite a bit of pure quartz I started wondering if King Canyon s granite had a less pure chemical mix than Yosemite s, which might also explain why it spalls and exfoliates differently, creating needle shaped peaks instead of domes.Now, just a few days ago, I finished
I actually didn t finish this Not being partial to theft, I had to leave it at the cabin However, what I did read was surprisingly interesting Fun to read about the history and geology while being surrounded by it. A handy, well illustrated roadside and trailside guide to the Sierra Nevada mountains Lovely little inserted maps with keys to identify geological features If you want to understand what happened when and what is happening now in the Sierra, this is your book and guide I think they could have done o
I read this years ago This book is highly readable and informative If you re on a Sierra trail, on a beach admiring the surrounding peaks or just curiousa about the magnificent mountains around you, you ll enjoy this read. A basic book on the Geology of the Sierra Nevada If you looking for something to introduce you to the geology of this awesome mountain then this is a good book for you If looking for advanced information look else where. Takes a process approach describing the geologic history of the Sierra Nevada plate tectonics, ocean floor, granodiorite plutons, volcanism, glaciation with examples shown through the Sierra, with special chapters on gold and Mono Lake. Select a rock from Panum Crater near US 395 by Mono Lake If it floats some rocks do , it s pumice. Really helpful for learning some of the geology, but so the history of the people who have explored the Sierra No wondering who various mountains are named after. This is one of my favorite geology books i recommend it to anyone interested in California geology, and certainly anyone interested in the Sierra Nevada mountains of California Though my trip to Yosemite has been cancelled due to a fire in the area, I have learned a great deal about the Sierra Nevada and really hope I do get a chance to visit in the not too distant future.
