Take a gander at the fruit of their non-critical labour!
It seems appropriate in the midst of winter to present you with a wintry option such as this. Norbert E. Yankielun, a research engineer for the U.S. Army Corps of Engineers, compiled this how-to manual on snow shelters of all shape and size. In it he provides tips on structural stability, customization (vanity igloo!), the effectiveness of different tools, and ease of construction.
Whether you're an old hand at igloo construction or just decided to embrace winter wholeheartedly, this book has something to teach you about snow appreciation.
