A round capstone, set in the middle of a small circular plaza, marks the resting-place of two time capsules buried here by the Westinghouse Electric Corporation -- one in 1938 (the first time capsule ever) and the second in 1965. They are packed with artifacts such as a slide rule (1938) and a Beatles record (1965).
The capsules themselves, 50 feet underground, have remained safe since their burial, although the capstone has occasionally been vandalized with graffiti. Some time capsule fans fret that global warming will leave this spot 30 feet underwater in 5,000 years (which is how long the capsules are supposed to remain buried). This will make them difficult to spot in the 70th century.
Westinghouse engineers designed the capsules to be corrosion- and leak-proof, so we'll just have to hope that someone surfing the Web in 6938 AD will read this page and dig them up.
