A Secret Hidden Mountains Of Millions Of Years Ago

Once a gold mine, today the Yukon is considered as a "treasure" of geologists because it kept sediments of millions of years ago. People remember "Klondike Gold Rush" when hundreds of thousands of women and men flocked to the mountains of Yukon, Canada in the late 19th century to seek luck. Today, people still go to the Yukon but for many different reasons compared to 100 years ago. Many people come because of history, they find stories related to the gold rush. Others visit the mountains, explore the natural world and wildlife such as bears, elk, lynx, mountain goats, foxes, musk cows, marmot ground squirrels

... Another group of visitors arrived Yukon to find luck but is a completely different "gold".



It is the geologist looking for sediment containing evidence of the "Snowball Earth" theory. For example, when the earth's climate changed and the surface froze around 650 to 750 million years ago, in July 2014, Vivien Cumming, a BBC correspondent and a few geologists at the two universities. Harvard and McGill went to Yukon to hunt for new evidence. That evidence could help them complete the picture of this bizarre period of climate change. Their destination was not easily accessible. The wide expanses of mountains make Yukon a wilderness, uninhabited, and difficult to navigate overland. Many mountains here do not even have names and many mountains have never been set foot The group determined the destination by studying aerial photos and geological maps, but with land never before.



Someone has discovered this method, the above method is very difficult exactly. The group plans to set up camp on the Wernecke Mountains in central Yukon, north of the small village of Mayo. This is the northern part of the Cordillera mountain system, a chain of mountains stretching from Alaska to the south of Mexico, and the first part of the trip required the group to travel by helicopter from northeast Mayo to Rackla, an open pit mine. The old heaven in the wilderness east of Yukon. The pilot was taken to the campsite by the pilot, and entered the mountains of 65 km. As the clouds got closer to the intended location, the clouds rolled to thicker. The pilot had to change direction to fly through thick clouds and around the mountain peaks. He doesn't seem to be flinching, but the geological team member is very scared when he flies over the high rocky peaks and suddenly meets the cloud cover.



After finding a flat place to land, the pilot took the crew safely to the ground. As the helicopter faded away, reporter Vivien realized that everyone had been "loving" weather, because where they arrived there was Nature and nature are difficult for the rescue crew to access, unless the weather is favorable for the helicopter to take off. This is where the crew stayed for several weeks exploring the Yukon. They named the camp Mordor because of the black peaks surrounding the campsite. The camp was set up on a high ground, more than 2,000 meters away from live trees. There is a lot of rocky soil here to observe and not covered by trees. Bears are also rare because the mountains are so high that there is no food for them, and people have spent a few days traveling a few hundred meters down the valleys. One day they walked back to their campsite when they saw a large brown shadow and heard the panicked cries of marmot ground squirrels.



At that time the group tried to escape, had to discuss for half an hour and meanwhile the animal did not move. In the end, the brave people took a closer look and discovered that in fact the large shadow was not a bear, but a large brown rock. That dinner was very happy and laughter because of this mistake. On the same day of the incident, the group found the first evidence of the "Snowball Earth" theory. Geological layers form on the seabed when sand and rocks accumulate, but when the earth is covered with ice, thin layers like sediments are less likely to be deposited. Whereas larger rocks lie on the surface of the ice, where they are carried as the ice moves. The moment the ice melted, these rocks fell to the ocean floor and stirred layers that formed before being deposited by new sediments. In this remote valley, large rocks in the crystalline sediment are disturbed by heavier rocks falling into the sediments of the seabed.



This is a rare geological phenomenon and a theory that helps to prove the Snowball Earth theory. The discovery by the Yukon geological team is not a treasure the way people have sought before in ”Klondike Gold Rush ". They came home after a month with buckets full of ice that had no currency value. However, for scientists looking for clues about the mysterious past, they are as valuable as gold..
