I cannot explain why we are re-posting this bit from last year's Bovine of the Week Series. Just accept that there is a good reason.
Yes, unlike the Musk Ox, the Yak is a bovine, and a cousin of the ancestor of our Western domestic cattle, the mighty Auroch.
Yaks come in a wild and domesticated form. 85% of these cold-climate creatures are said to be in China, and are still used for plowing, meat, milk, wool, and as beasts of burden. They are capable of hybridizing with domestic cattle, yielding a breed which is commonly used as a pack animal in Tibet.
Why yurts with yaks? They begin with a Y. Yurts are Mongolian houses, of course, but I recently learned that you can buy plans for them, and the structures, from several American manufacturers, such as Pacific Yurts. Cozy dwellings for snowy places, cheap and practical - but I'll take a log cabin.
