This is a great book that covers all the aspects required to understand avalanche safety and the elements of knowing what areas will avalanche. Great book.
- It is well formulated: At first I was impressed by the book, and I found interesting points in it. Birkeland). It really looked like someone that felt himself undereducated trying to compensate by putting in technical termology that sounds right, or just simple five or six syllable words like "anisotropic" to impress, rather than clarify. Where the author would have been completely right without the frequent attempts to be over-precise. In the chapters about heat transfer, radiation and other physical processes in snow there were frequent subsentences and parenthesis that at first seemed to be there to explain or clarify things, but my spontaneous thought when reaching them was "What. But that is two different things.", or "But that's not right."After a while I recognized whole subsentences, or even whole sentences, that seemed to have no other reason to be there than to impress and dazzle the reader. As a reviewer said: the science sounds like something one may say "at a dinner party". The science seems to end up "not right" too often.
- A better book with regards to readability, but perhaps also with regards to the science, is Bruce Tremper's "Staying Alive in Avalanche Terrrain", and clear well written pieces can also be found in books like "Field Guide to Snow Crystals" by Edward R LaChapelle. - There is lot of good stuff in this book, but it shouldn't be put in such high regard for it's "science" as most readers and reviewers seem to do. - I expect to find more good stuff in this book, but it is really not indispensable unless it is your job to release controlled avalanches. Is the style of the text deliberately chosen to dazzle and then scare away the reader. But when trying to use it as extra literature when reading some micro-meteorology I got deeper into the text; and what looked interesting (or impressive) turned out to become frustrating and embarrassing. Never wrong, but too often "not right".
As an academician that also ski and move around a lot in avalanche terrain I felt outright embarrassed. (I was so tired after a couple of hours of studying the text for the good stuff, while navigating around the weird parts that I really had to sit down and relax with a pure scientific paper about snow by Karl W. It isn't the science that makes the text heavy, it's the urge to be eloquent that do it. The backcountry traveler and the pure academically interested will find better texts out there.
We are counseled to pay attention to local conditions, but we are also told that if our tests show a stable snowpack they should be discounted. Nowhere do we find any specific guidance in using instability tests or snowpack profiles in making decisions.
That said I think the book fails in two important ways. There is a lot of information in this book, and it's certainly a must have for anyone who wants to be able to make their own decisions about travel in avalanche terrain.
The authors' reluctance to inlude anything that even smells of math turns the science sections into collections of things one might say about avalanche science at a dinner party, but otherwise not very useful when it comes to applying the science to avalanches.When it comes time for the book to lay out a paradigm for making decisions in avalanche country, we find a confusing mess of very abstract decision schema. It fails at explaining the current state of the science behind avalanches, and it fails at giving end users a systematic way to utilize data from snow instability tests.We get bits and pieces of the science behind avalanches but at a very superficial level.
You learn something about the sorts of things scientists think about avalanches without learning the why and wherefore of it. This lack of guidance is exacerbated by the skeptical stance the book takes towards stability tests.
It's not clear how stability tests could ever yield anything other than a no-go decision given that sort of paradigm, and the book needs to do more to explain how to navigate the grey zone if it to be useful as a handbook for making decisions.So while this is an indispensable book, it could really use more work, and anyone wanting to understand the contents should probably be ready to dig into the nuts and bolts of the underlying science a bit more using other resources.
This handbook is a comprehensive compilation of the state of current science regarding the snow avalanche phenomenon. Required reading for most level 2 avalanche courses, and highly recommended for casual backcountry users, this book really excels in the figures and diagrams included. Be warned, however, that the material is rather dense - not really a sunday read.
Every winter we hear of people who have become the victim of an avalanche while skiing, snowmobiling, or camping in mountainous country where a landslide of snow roars down off a mountain side faster than anyone can move out of its way. Co-authored by David McClung (a professor in the Department of Geography and leader of the avalanche research group at the University of British Columbia) and Peter Schaerer (a senior research officer and head of the Avalanche Research Center of the National Research Council of Canada), "The Avalanche Handbook" is now published and available in a newly updated and expanded third edition that includes all the latest information, techniques, and research on understanding the nature of avalanches, as well as how to avoid and/or survive encounters with them. Readers will learn about the character and effects of avalanches, snow formations, snowpack analysis; the use of multiple transceivers along with other search and rescue techniques and equipment; the elements of avalanche forecasting, backcountry forecasting, and the decision-making process with respect to assessing avalanche possibilities; snow slap instability, terrain variables, skier triggering of avalanches, and the nature of avalanche motion. The informative and thoroughly 'reader friendly' text is superbly organized and nicely illustrated making "The Avalanche Handbook" essential and very strongly recommended reading for anyone venturing into mountain country in winter.
