The North Slope is mostly tundra peppered with small villages. The
area is known for its massive reserves of crude oil, and contains both
the National Petroleum Reserve–Alaska and the Prudhoe Bay Oil Field.
Barrow, the northernmost city in the United States, is located here.
The Northwest Arctic area, anchored by Kotzebue and also containing
the Kobuk River valley, is often regarded as being part of this
region. However, the respective Inupiat of the North Slope and of the
Northwest Arctic seldom consider themselves to be one people.
