Having mostly to do with dog-sledding and a series of inserted storiesĀ on the Chukchi of northeastern Siberia and their devastation by the Soviets. Of course the Soviets devastated everybody but it was the first time I had ever read details of the Chukchi.
I believe that the Chukchi language is the only one related to a North American language, i.e. Inuit, or Inupiat.
Descriptions of learning how to run a dog team are very good.
