Query: What a find!

This is one of the lesser-known books on the JMT, and I bought it with some trepidation. But boy, was I pleasantly surprised! This is a true little gem. I have thru hiked the Muir Trail from north to south and found this book is very informative and containing some very useful information. The maps are adorable and hand-drawn, but highly accurate. The book is not marketed as being geared towards novices, but there's no doubt it would benefit a beginner and be less beneficial to a seasoned backpacker. But even old pros with be delighted with the format and presentation here.There are route descriptions of each facet of the trail, such as explaining the drop off points, elevation gains and topography of Thousand Island Lake in Mammoth to Tuolumne Meadows in Yosemite. You could do a thru hike without this guide, but if you're the least bit apprehensive, then this would ease your worries. Even if your an armchair JMT thru hiker, I think you'd enjoy this nifty book.
