Built in the mid-1920s, Germany's Nurburgring, and specifically the Nordschleiffe (or North Course), is one of the longest, most intimidating, and certainly most dangerous race tracks on earth. It remains unknown exactly how many people have died there in their pursuit of passion, but it's a lot. Some say the number ranks in the hundreds. Sir Jackie Stewart nicknamed it the Green Hell, which accurately sums up the juxtaposition of lush vegetation and the ever-present danger. These shots were purportedly taken in 1967 by a Porsche engineer named Jack Moody. Not much else is known about them, but they illustrate both the danger of the course and the awesome challenge that still makes it a driving mecca.
