ABC has some photos of the quarry, or you can watch a two-minute video with relatively poor footage of the site (and two guys who can’t correctly pronounce the object of the discovery). 

BiblePlaces.com has some exclusive photos of the quarry area, with thanks to Aubrey Laughlin for sharing them with us.  Click on each photo for a higher-resolution version, which you are free to use for personal and educational purposes.

I have been asked where exactly the quarry was located.  Here are two maps from Google Earth that show the area of the quarry, about 2 miles (3 km) north of the Old City.  You can click on each for a larger view.

General view.  Note the highway to the east of the quarry is similar to the ancient route (known sometimes as the Central Ridge Route or the Road of the Patriarchs).

Closer view, which will be helpful if you’re in the neighborhood and want to see it yourself.
