Location in Alaska

The National Petroleum Reserve Alaska (or NPR-A) is a monstrous 23 million acre region located north of the Brooks Range, largely on what is called Alaska’s Arctic North Slope. It was originally set aside by President Harding as an emergency oil supply for the US Navy.

NPR-A

The average person knows little about the region, and it is huge. It is a land rich in wildlife and serves as a critical habitat for the Western Arctic Caribou Herd, which fluctuates in population between 200-400 thousand animals. All of the National Petroleum Reserve Alaska photos are available for purchase as stock photography, or as fine art prints to display in your home or office.
