National Petroleum Reserve photo gallery
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 north slope. It was originally set aside by president Harding as an emergency oil supply for the US Navy. 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 is near 400,000 animals in total.
