Oil Spills Past and Present

The Gulf of Mexico is awash in oil, resulting from the April 11, 2010 explosion on the Deepwater Horizon drilling platform, owned and run by BP. The Society has published content that relates to oil spills and the oil industry. Find answers to questions such as how the Exxon Valdez oil spill was viewed immediately after the accident and in retrospect, or why there's a large Vietnamese community along the Gulf Coast. In a trip back to San Francisco just after the Summer of Love, see how important community involvement was in cleaning up a 1971 oil spill in San Francisco Bay. Then take a trip around the world and survey the global oil scene in places as diverse as Siberia, the Niger Delta, and the North Slope of Alaska.
The content is divided into the five categories below. If there is online content, a link will be provided; click on the "How to Locate NG Content" for more assistance.

Left on Everest

For 60 years climbers have dumped gear and trash en route to the top of Mount Everest, often in the low-oxygen “death zone” above 26,000 feet, where shedding a few pounds can preserve precious energy.
In recent years melting ice has begun to reveal the scope of the high-altitude imprint, exposing oxygen tanks and other long-frozen jetsam. Though tons of refuse are removed annually from base camps, last spring two Nepali groups, Extreme Everest Expedition and Eco Everest Expedition, targeted the peak’s upper reaches and hauled down seven tons of waste, including debris from a 1973 helicopter crash.
Nepalis are also concerned about corpses collecting on the mountain they consider holy. Since 1996 some 80 climbers have perished above base camp; most remain near the spot they died. In May two bodies, a Swiss and a Russian, were removed along with a pair of unidentified arms, one wearing a watch. Bringing back corpses was long considered logistically unfeasible, says Linda McMillan of the International Mountaineering and Climbing Federation. But as traffic on Everest has risen, she notes, so too has the desire to clean it. —Peter Gwin
