September 19 - Discovery of "Ötzi the Iceman"

Posted on September 19, 2020

The Alps are gorgeous mountains, known as the setting for the Sound of Music, Heidi, and bunches of other stories and movies, for the Matterhorn, and European ski destinations! 

And the Alps are where a mummy of a man who lived more than 5,000 years ago was found. Modern scientists have dubbed the man Ötzi, because the specific section of mountains where he was found is called the Ötzal Alps. 


You may associate mummies with Ancient Egypt, but some mummies were not carefully created with spices and long strips of cloth - instead, they were somehow created by unusual natural conditions. Ötzi is the oldest natural mummy ever found in Europe.

Found on this day in 1991 by two German tourists, Ötzi was assumed to be a more recently dead body of a mountaineer. Of course the tourists reported the death, and a mountain gendarme (a sort of police officer that maintains a mountain hut on the border of Austria and Italy) went up the next day to retrieve the body. He had a pneumatic drill AND ice-axes but was not able to remove the body from the ice, at least partly because of bad weather. The next day, eight groups traveled to the body in order to plan the extraction on the next day.


Think how surprised those German tourists must have been when they found out how old the body they had found actually was!

The reason that Ötzi had mummified instead of breaking down was - as you may have guessed - that he was covered with ice shortly after he died. Scientists think he was murdered, since an arrowhead was discovered in one of his shoulders.

It's often startling how much scientists can learn from ancient ruins or remains! They can estimate Ötzi's age, height, and weight at the time of his death; he was about 45 years old, only 5 feet 3 inches (160 cm) tall, and only about 110 pounds (50 kg). 

From analysis of pollen, dust grains, and other items embedded in his tooth enamel, scientists have good guesses about where Ötzi spent his childhood and a different location where he lived as an adult. Scientists were able to figure out what Ötzi ate during his last two meals - in each meal he ate meat, grains (probably some sort of bread), roots, and fruits. The foods included meat from ibex, chamois, and red deer. Frozen alongside the body are kernels of sloes, which are small plum-like fruits, seeds of flax and poppy and wild berries, and grains of wheat and barley. It's likely that Ötzi was carrying food in some sort of pouch or pocket that froze along with him.

Scientists can even figure out about where and when the most recent meal was eaten: in a mid-altitude pine or other conifer forest, in the spring or early summer. Scientists know that because of very fresh, well-preserved grains of pollen mixed in with food.

Scientists may even have leads on Ötzi's profession. He had both copper particles and arsenic in his hair, and his axe blade was 99.7 % pure copper. These clues indicate that he may have been involved with copper smelting. The wear on Ötzi's leg bones make it apparent that he routinely walked long distances, which might indicate that he was a shepherd.

Believe it or not, scientists also have indications of medical problems, including lactose intolerance, and timing of recent illnesses. 

Also, Ötzi had 61 tattoos on his body. For a while there, he was the oldest known human mummy with tattoos, but since his discovery other truly ancient tattooed mummies have been found.

The tattoos don't seem to be pictures like so many modern ones, but patterns of lines:





March 12 - "Because We Can..."?

Posted on March 12, 2018



I noticed that today is the anniversary of the first time that the North Face of the Eiger was climbed in the winter.

To give this context:

The Eiger is one the Alps in Switzerland.

The Matterhorn was the first of
the famous Six North Faces of the
Alps to be climbed.

The Matterhorn is the highest peak
in Western Europe and the most
famous mountain in Europe, which is why
its mini-replica is found in Disneyland.
It has the biggest north face in the Alps. A "face" is a vertical or sloping side of a mountain or cliff. There are six famous north faces in the Alps, and three of them are way, way more difficult to climb. The Matterhorn is one of the three super difficult north faces to climb, and the Eiger is another of them.

There was a lot of hubbub among climbers to be the first to climb one of these famous faces; the first ascent of Nordwand ("North Face" in German) or "Eigerwand" (short for "Eiger North Face" in German) was in July of 1938.

The first winter ascent of Nordwand was accomplished on this date in 1961. It took the climbers six days to make the climb - no data on how long it took to get down!

The thing is, at least 64 climbers have died trying to climb the North Face. It is sometimes called Mordwand instead of Nordwand - that translates to "Murderous Wall"! The dangers include avalanches, storms/blizzards, freezing temperatures, and rockfall / landslides.


So...if you, like me, want to ask "why-oh-why?" do some people insist on facing all these dangers...I think a common response is "because we can." (Even if, it turns out, a few people couldn't.)

The record books are full of first female climber to ascend Nordwand, first Czech climbers to do so, first Americans, first all-female group, first with primitive equipment, first solo ascent, first winter solo ascent, first female solo ascent, fastest ascent, first BASE jump from the top - and about a bajillion more "firsts." Some people just feel that lure to challenge themselves, some want to gain a bit of fame or get their name in the record book, some love climbing and do it all the time and just need a new mountain to conquer.

By the way, nowadays many climbers are choosing to climb Eigerwand in the winter because the crumbling rock wall is actually strengthened by ice!

July 27 – Happy Birthday, Thomas George Bonney

Posted on July 27, 2014

So...if you learn a lot about something while having fun doing your hobby, you too might end up with a university job teaching that something, a Wikipedia article about yourself, and a lake in Antarctica named after you!

Born on this date in 1833, the English geologist Thomas George Bonney was a math teacher who loved to hike around alpine (high mountain) regions, studying the rocks there.

He got so knowledgeable about alpine geology, he became a geology lecturer at a college and later a professor of geology at a university. He also became the president of the Alpine Club.

Bonney also wrote a biography of geologist Charles Lyell, who was the most important geologist of his time. Lyell came up with the concept of uniformitarianism, which is the idea that the Earth was shaped by the same forces and processes that we see happening today. Rather than assuming that the Earth's landforms were created very suddenly by short-term, violent events like a catastrophic global flood, Lyell suggested that they were created slowly and gradually by processes such as erosion, which we see occur now. Lyell was one of the first geologists to realize that the Earth was older than 300 million years.

Lyell was a friend of and important influence on biologist Charles Darwin.

The word alpine comes from the Alps

When we talk about alpine animals, alpine plants, and alpine geology being the animals, plants, and rocks found on high mountains, we are using a word coined by Europeans for the highest mountains in Europe: the Alps.

The Alps are a mountain range that stretch from Austria and Slovenia, in the east, through Switzerland, Liechtenstein, Italy, Monaco, Germany and France, in the west.








Like many mountain ranges, the Alps were created when two tectonic plates collided. Remember, geology has a lot of very slow (yet unstoppable) processes, and the collision of two plates is one of them. It's not a dramatic SMASH! BANG! collision -- but it goes on and on year after year after year after thousands and millions of years.

In the case of the Alps, the African plate and the Eurasian plate moved slowly toward one another, probably at about the rate of fingernail growth. They collided while traveling toward one another at a rate of less than an inch to a few inches PER YEAR.

(Of course, once in a while tectonic plates move quickly, slipping past each other in a juddery, skittery event called an earthquake. But that's generally when plates are moving alongside each other.) 

In the case of colliding plates, it's hard to see any change within a human lifetime. But as they collide, the plates push upwards in a series of folds, forming mountains over millions of years.

Here is what is special about the Alps: 

They are the most densely populated mountain area in the world.

The Alps are middle aged mountains. (For comparison, the Rockies and Himalayas are considered young – at 10 to 25 million years of age. The Urals and Appalachians are old, at more than 200 million years of age. The Alps began to form about 40 million years ago.)

About 11 million people live in the Alps, making their living through forestry, pasturing sheep, cattle, and other animals, and of course tourism. Ski resorts and other winter tourism is especially popular, but in the summer the Alps are filled with hikers and walkers, cable-car riders, and para-gliders.



Because of the huge numbers of tourists and the large all-year population, the Alps is considered the most threatened mountain chain in the world.

I am thrilled to inform you that, although I have only ever been to the Alps in the summer, I was up high enough during a storm that it snowed on us! I never thought I would get to say that I was snowed on in the Alps!

Tourists can even enjoy the INSIDES
of the Alps. This tunnel was carved
into a glacier. I visited tunnels and under-
ground caves of a salt mine in the Alps.
