How Is A Lake Saltier Than The Ocean?

Courtesy of Nicolene Steynberg about the Madswimmers hiking up Mt Ojos del Salado in Argentina.

The Madswimmer group of 7 South African high-altitude swimmers, 2 medics, 4 support climbers, a tour guide and a cameraman found an interesting phenomenon up on their way to Mt Ojos del Salado in the Andes Mountain.

In their attempt to complete the highest swim in the world in Argentina, the Mt Ojos-Madswimmer team swam and kite surfed on their way to Mt Ojos, highest volcano in the world. They found the water to have a very high degree of salinity, an estimated 11 times as high as the ocean.

Nicolene Steynberg explained why. "There are many volcanoes in the area. With the soil and water naturally pans out contains lots of salt and the water doesn’t have an outflow."

But the trek getting to their location at 6,400 meters is getting tough. "Nobody said the highest swim will be an easy swim. They are facing challenging conditions; it is very cold. They are now on Mt Tres Cruses in search of a backup [swim location] in case the Ojos location is frozen solid. Guide Edwardo found a lake in a volcanic crater at 5,909 meters above sea level after a very difficult climb. The swimmers will still need to climitise before attempting to reach their [destination].

The Other Shore

The Other Shore follows world record holder and legendary swimmer Diana Nyad as she comes out of a thirty-year retirement to re-attempt an elusive dream: swimming 103 miles non-stop from Cuba to Florida without the use of a shark cage. Her past and present collide in her obsession with a feat that nobody has ever accomplished. At the edge of The Devil’s Triangle, tropical storms, sharks, venomous jellyfish, and one of the strongest ocean currents in the world, all prove to be life-threatening realities. Timothy Wheeler’s documentary brings Diana Nyad’s extraordinary adventure to life as Diana sets out to prove that will and determination are all you need to make the unimaginable possible.

2014 Open Water Swimming Almanac

An Almanac for Open Water Swimming

An almanac is essentially a body of knowledge which is so complete that it enables people in different fields to make predictions about the future of their respective industries.

This, for example, was the purpose of the traditional farmers almanacs. It enabled farmers to determine as accurately as possible which crops to plant for the greatest harvests in a given year.

But the farmers almanac was just one example among many.
There are, of course, many different kinds of almanacs.

In fact, there is even one for open water swimming...

The trends are very clear.
The tide is rising for open water swimming.
