Science fiction writer Kim Stanley Robinson calls his time in the mountains 'hours stolen from the gods.' For me, this book was a touchstone for what I suspect will be a lifetime's interest in geology. Robinson turns out to be an enthusiastic amateur-expert on psychogeology, alpenglow, and traversing tallus and scree. A gold mine for any hiker, mountaineer, or reader of John Muir or Gary Snyder—and if you're at the intersection of any of those things, this book is a no-brainer. Buy in hardcover. Appreciate the stunning color photographs.
