How does the glacier hold the couple's body for 75 years?

Conditions in the heart of the glacier as well as the body reaction turn the body of the Swiss couple into mummies for 75 years.

Last week, during a routine inspection trip, the ski lift technician of the Glacier 3000 resort in Switzerland discovered a collection of black rocks near the Tsanfleuron glacier west of the Bernese Alps, according to New. York Times. On closer inspection, the technician discovered that the stone blocks were actually mummies.

DNA testing helped confirm the mummy belonged to couple Marcelin and Francine Dumoulin , went missing after leaving home to feed cattle on August 15, 1942.

The possibility that the two Dumoulin people fell into a crack is still a mystery, but maybe a blizzard has covered them, making the search team unable to see the couple. Whatever happens, the water in their body eventually froze. However, ice crystals in their tissues are certainly not in a fixed state, according to Dan Fisher, professor of Earth and Environmental Sciences at the University of Michigan, who does not participate in the identification of the remains.

"At first the tissue has a high amount of water, but the water will freeze, and in many cases, under freezing conditions, when surrounded by air with low water vapor, ice tissue in the tissue can be promoted. Flower, " Live Science quoted Fisher. Sublimation is the process in which hard ice directly converts into water vapor without turning into a liquid. In other words, the tissues dry out, according to Fisher.

In this case, both dry and cold conditions prevent bacteria and active molds and chemical processes from decomposing human tissue that contribute to perfect preservation of the victim's body.

In addition, the two bodies are still relatively intact because the Tsanfleuron glacier is quite stable, although slow-flowing glaciers frequently move. They move forward when new snowpacks form more than snow and retreat in the opposite case, according to Martin Callanan, associate professor of archeology at the Norwegian University of Science and Technology.

The retreat of the glacier facilitates researchers to look back. In 2003, at the Schnidejoch glacier less than 32km from the Tsanfleuron glacier, researchers discovered coins, leather, a piece of wooden bowls and a set of bows and arrows. These objects are the most recent dating from the Middle Ages and the farthest is the Neolithic period nearly 4,500 BC.

Callanan said that the increase in the number of objects discovered in the glacier is the result of global warming . Global temperatures in 2014, 2015 and 2016 continue to set the hottest record of the planet since 1880, according to the US National and Atmospheric Administration. This warming makes the world's glaciers shrink.

The discovery of the Dumoulins couple's body brought great comfort to their daughter Marceline Udry-Dumoulin. Udry-Dumoulin, one of Dumoulins' seven children, was only 4 years old when her parents disappeared. After they disappeared, the local rescue team searched for more than two months but had no results.
