9 Deep Facts About the Dead Sea

The Dead Sea is one of the most unusual lakes in the world. Located at the lowest point on Earth, tourists from around the globe flock to this hypersaline phenomenon, which borders Jordan to the east and Israel and the West Bank to the west. Dive into these nine fascinating facts about the "Salt Sea."

1. The Dead Sea was formed by a rift in the Earth's crust.

The Dead Sea was formed as two of Earth's tectonic plates, the African and Arabian plates, began to pull apart more than 3 million years ago. That action created a graben (the German word for ditch), which then connected to the Mediterranean Sea. Over millennia, tectonic activity isolated the graben from the sea, forging an inland lake. Today the Dead Sea is fed by the Jordan River at its northern end.

2. The Dead Sea is located at the lowest point on Earth.

The surface of the Dead Sea is 1300 to 1400 feet below sea level (for comparison, Death Valley, the lowest point in North America, is 282 feet below sea level). The deepest part of the Dead Sea lake bed is about 2300 feet below sea level. The Dead Sea, measuring about 50 miles long and 11 miles at its widest point, lies between the Judaean Hills to the west and the Transjordanian highlands to the east.

3. Dead Sea water may be good for your skin.

The Dead Sea is about 34 percent salt. For millennia, people have reported health and skin benefits from exposure to Dead Sea water and mud. Some studies have shown that taking a dip in Dead Sea water, which is rich in magnesium salts, can reduce inflammation and dry skin and increase the skin's ability to hold moisture.

4. The Dead Sea is one of the world's saltiest bodies of water.

No need for flotation devices here. People's bodies are more buoyant in the Dead Sea because of the high concentration of dissolved mineral salts. At its surface, the Dead Sea is five to nine times more saline than seawater; the deeper you go, the saltier it gets. Rather than swim, visitors simply float on the surface.

5. The Dead Sea has been a place of refuge since biblical times.

The Dead Sea is cited in the Hebrew Bible during the rule of King David as a place where he sought refuge. This famous sea is also mentioned in other biblical books throughout history. The first tourist to visit the Dead Sea was most likely Abraham.

6. The only thing that can survive in the Dead Sea is bacteria.

No recognizable creatures can survive in the Dead Sea, which means no jumping dolphins, no swimming fish, and no seaweed to get stuck between your toes. The massive levels of salt prevent the existence of all life forms, except some bacteria discovered in recent years. Needless to say, don’t drink the water!

7. Dead Sea mud is a hit with tourists.

Almost as famous as the sea itself are the images of tourists slathering mud on their bodies, letting it harden, and then rinsing it off in the sea. The deposits of black mud come directly from the seabed and it is high in magnesium, sodium, potassium, and calcium.

8. The Dead Sea may be the biggest free spa on Earth.

With all that mud, the Dead Sea is the world's biggest natural free spa. But should you feel the need to indulge in further spa treatments, there are multiple hotels in the area that offer rejuvenating spa services, including the famous Ein Gedi Hotel.

9. Yes, the Dead Sea Scrolls were found here.

The Dead Sea Scrolls were found hidden in a cave in Qumran and contain some of the oldest known copies of the Hebrew Bible. Portions of the Dead Sea Scrolls now make the occasional tour at various museums so scholars can continue to study them.

15 Memorable Ruth Bader Ginsburg Quotes

Supreme Court justice, feminist, and all-around badass Ruth Bader Ginsburg passed away on September 18, 2020 from "complications of metastatic pancreas cancer," the Supreme Court said in a statement. Over the course of her 87 years, she smashed glass ceilings and delivered plenty of wisdom—inside the courtroom and out. Here are some of our favorite quotes from the Notorious RBG.

1. On her mother

"My mother told me two things constantly. One was to be a lady, and the other was to be independent. The study of law was unusual for women of my generation. For most girls growing up in the '40s, the most important degree was not your B.A., but your M.R.S."

— via ACLU

2. On turning rejection into opportunity

“You think about what would have happened ... Suppose I had gotten a job as a permanent associate. Probably I would have climbed up the ladder and today I would be a retired partner. So often in life, things that you regard as an impediment turn out to be great good fortune.”

— In conversation with Makers

3. On female Supreme Court Justices

"[W]hen I’m sometimes asked when will there be enough [women on the supreme court]? And I say ‘When there are nine.’ People are shocked. But there’d been nine men, and nobody’s ever raised a question about that."

— In an interview with 10th Circuit Bench & Bar Conference at the University of Colorado in Boulder, via CBS News

4. On dissenting opinions

"Dissents speak to a future age. It's not simply to say, ‘my colleagues are wrong and I would do it this way,’ but the greatest dissents do become court opinions."

— From an interview on Live with Bill Maher

5. On criticism and not getting a majority vote

"I’m dejected, but only momentarily, when I can’t get the fifth vote for something I think is very important. But then you go on to the next challenge and you give it your all. You know that these important issues are not going to go away. They are going to come back again and again. There’ll be another time, another day."

— via The Record [PDF]

6. On having it all

"You can't have it all, all at once. Who—man or woman—has it all, all at once? Over my lifespan I think I have had it all. But in different periods of time things were rough. And if you have a caring life partner, you help the other person when that person needs it."

— From an interview with Katie Couric

7. On discrimination

"I ... try to teach through my opinions, through my speeches, how wrong it is to judge people on the basis of what they look like, color of their skin, whether they’re men or women."

— From an interview with MSNBC

8. On gender equality

"Women will have achieved true equality when men share with them the responsibility of bringing up the next generation."

— via The Record [PDF]

9. On feminism

"Feminism … I think the simplest explanation, and one that captures the idea, is a song that Marlo Thomas sang, 'Free to be You and Me.' Free to be, if you were a girl—doctor, lawyer, Indian chief. Anything you want to be. And if you’re a boy, and you like teaching, you like nursing, you would like to have a doll, that’s OK too. That notion that we should each be free to develop our own talents, whatever they may be, and not be held back by artificial barriers—manmade barriers, certainly not heaven sent."

— In an interview with Makers

10. ON her fellow Supreme Court Justices

"We care about this institution more than our individual egos and we are all devoted to keeping the Supreme Court in the place that it is, as a co-equal third branch of government and I think a model for the world in the collegiality and independence of judges."

— In an interview with C-Span

11. On the 5-4 Hobby Lobby ruling

"[J]ustices continue to think and can change. I am ever hopeful that if the court has a blind spot today, its eyes will be open tomorrow."

— From an interview with Katie Couric

12. On those Notorious RBG T-shirts

"I think a law clerk told me about this Tumblr and also explained to me what Notorious RBG was a parody on. And now my grandchildren love it and I try to keep abreast of the latest that’s on the tumblr. … [I]n fact I think I gave you a Notorious RBG [T-shirts]. I have quite a large supply."

— In an interview with NPR’s Nina Totenberg

13. On being an internet sensation

"My grandchildren love it. At my advanced age—I’m now an octogenarian—I’m constantly amazed by the number of people who want to take my picture."

— From an interview with the New Republic

14. On retirement

"Now I happen to be the oldest. But John Paul Stevens didn’t step down until he was 90."

— From an interview with The New York Times

15. On how she'd like to be remembered

"Someone who used whatever talent she had to do her work to the very best of her ability. And to help repair tears in her society, to make things a little better through the use of whatever ability she has. To do something, as my colleague David Souter would say, outside myself. ‘Cause I’ve gotten much more satisfaction for the things that I’ve done for which I was not paid."

— From an interview with MSNBC
