Oregon's Ancient Falls Vanished in a Single Afternoon

On March 10, 1957, the gates of The Dalles Dam closed on the Columbia River.

What Happened to Bed Bath & Beyond?

For over a decade, Bed Bath and Beyond trained its own customers never to pay full price. The company's iconic big blue twenty-percent-off coupons were mailed out so relentlessly, and honored so unconditionally, that shoppers stopped buying anything without one in hand. When new executives finally cut back on the coupons in 2019 to protect margins, sales did not dip. They collapsed. The company had not built customer loyalty. It had built coupon dependency, and going through withdrawal turned out to be fatal.

They Built an Elementary School on Twenty-One Thousand Tons of Buried Poison

In 1953, Hooker Chemical sold the Love Canal site to the Niagara Falls school board for one dollar.

Nobody told the parents about the warning in the deed.

A Dog Walk in the Alps Led to the Space Program's Favorite Invention

Area 51: The Secret Aircraft That Started the UFO Myth

His fourteen year old cousin Eric Wolfgang grabbed his arms and pulled him out.
