The area's extreme remoteness, great size, and sparse population have shaped the North Dakota character from the beginning of settlement a century ago.

Today, as world shortages of food and fuel raise new possibilities--and new problems--North Dakotans face the future with the cautious optimism they learned long ago in sod houses and cold winters on the far northern edge of their country.
