Axel Heiberg is a big island.
It sits in the cold Arctic Ocean.
Long ago, tall trees grew there. The land was a wet forest. Some trees grew for a long time.
Now, the trees are very old. They are not stone. The cold air kept them like mummies.
Scientists visit the island to study. They look at the old wood. They also look at the ice.

Axel Heiberg Island is a very large island.
It sits in the Arctic Ocean. It is part of the Qikiqtaaluk Region in Canada. This island is the 32nd largest in the whole world.
Long ago, this place was a wet forest. Tall trees grew there for many years. Some trees lived for 1,000 years! The climate was warm back then. Now, the island is cold and dry.
The old trees did not turn into stone. Instead, the cold air kept them like mummies. Scientists call this mummification. They have even found DNA in the old leaves.
Many scientists visit the island to learn. They use the McGill Arctic Research Station. They study the ice and the ground. They also look at a place called Lost Hammer Spring. This spring is very salty and very cold. It stays below freezing! Scientists think this spring is like parts of Mars. Studying it helps them learn about life in space.
People do not live on the island. In the past, the Inuit lived there. Now, it is a quiet place for science.
Axel Heiberg Island is a huge place in the Arctic Ocean.
It is part of the Qikiqtaaluk Region in Nunavut, Canada. This island is the 32nd largest island in the whole world. It is also the seventh largest island in Canada. The island is a member of the Sverdrup Islands and the Queen Elizabeth Islands. It sits in a very cold part of the north.
Long ago, this island looked very different. During the Eocene period, a forest of tall trees grew here. These trees reached up to 30 meters in height. Some of these trees may have lived for 1,000 years. The climate was warm, but the winters were still dark for three months. As the trees fell, fine sediment covered them. The cold, dry air kept them from turning into stone. Instead, the trees were mummified. This means they were preserved like mummies rather than becoming stone fossils.
Many explorers have visited this island over the years. The Inuit lived here in the past. Later, Otto Sverdrup explored the island in 1900 and 1901. He named it after Axel Heiberg, who helped pay for the trip. Norway claimed the land until 1930. In the 1940s, the United States Army Air Forces took photos from the air. In 1955, two geologists traveled across the middle of the island. Later, scientists from McGill University built a research station in 1960. This station helps people study the ice and the ground.
Scientists find many amazing things on the island. They have found fossils of an ancient turtle called Aurorachelys. They also found a bone from a bird named Tingmiatornis. Researchers have even found DNA in the ancient Metasequoia wood. This wood is almost identical to modern plants. One special place is the Lost Hammer Spring. This spring is very salty and stays below freezing. It is one of the coldest and saltiest springs in the Arctic.
This island helps us learn about other worlds. The Lost Hammer Spring is like a place on Mars. It is used as a Mars analogue for studying life. This means scientists use it to test tools for space. They also study the White Glacier in the Expedition Fiord area. The ice there is very thick. The island is a quiet place where people study the Earth and space. Nunavut is now looking at ways to protect the fossil forests. They might even make a park called Napaaqtulik.
Axel Heiberg Island is a massive, uninhabited landmass located in the Arctic Ocean. It sits within the Qikiqtaaluk Region of Nunavut, Canada. This island is a major part of the Sverdrup Islands and the Queen Elizabeth Islands. It ranks as the 32nd largest island in the entire world. Within Canada, it is the seventh largest island.
The island is a site of immense scientific importance. It contains unique geological features and ancient biological records. These records help us understand how the Earth has changed over millions of years.
The island is famous for its unusual fossil forests from the Eocene epoch. Over 40 million years ago, a high-latitude wetland forest flourished here. The climate during this period was much warmer than the Arctic is today. However, the winters were still dark for three continuous months. Tall trees grew in these wetlands, reaching heights of up to 30 meters. Some of these ancient trees may have lived for 500 to 1,000 years.
The way these plants were preserved is very special. Usually, fossils turn into stone through a process called mineralization. However, many specimens on Axel Heiberg Island lack this mineralization. Instead, the trees underwent mummification. As the trees fell, fine sediment covered them. The cold and dry Arctic climate then preserved them in this state. This process allows scientists to study the plants in a way that stone fossils do not allow. Researchers have even found double-strand DNA molecules in Metasequoia fossil leaves. When scientists compared the DNA of this ancient wood to modern plants, they found them to be almost identical.
Human history on the island involves many different groups. The Inuit inhabited the island in the past. Later, the explorer Otto Sverdrup visited the island during 1900 and 1901. He named the island after Axel Heiberg, a financial director for a Norwegian brewery. Norway claimed the territory until 1930, but it is now part of Canada. In the late 1940s, the United States Army Air Forces conducted aerial photography through Operation Polaris. In 1955, geologists N.J. McMillan and Souther traveled the interior during Operation Franklin. McMillan made the earliest published glaciological observations of the Bunde Glacier.
Research continues today through the McGill Arctic Research Station. This station was established in 1960 near Expedition Fiord. It includes a research hut, a cookhouse, and two temporary structures. The station typically accommodates between 8 and 12 people. During the early 1960s, the population at the station reached 20 people. The station is active from March to August each year. Scientists use the station to study polar geomorphology, geology, and glaciology. They also study permafrost, climate change, and polar microbiology.
Axel Heiberg Island also serves as a vital Mars analogue for astrobiology. This means the island's environment helps scientists study the possibility of life on other planets. One significant site is the Lost Hammer Spring in the central west region. This spring is the coldest and saltiest of all described Arctic springs. It features a perennial hypersaline discharge of 24% at subzero temperatures. The spring flows through a high, cone-shaped salt tufa structure. Microbes found here do not need oxygen or organic material to live. Because these microbes use simple inorganic compounds, the spring mimics conditions found on Mars, Europa, or Enceladus.
The island's landscape is also shaped by massive ice formations. The White Glacier is a valley glacier located in the Expedition Fiord area. It is a very large glacier with an elevation range that is nearly unmatched. Only the Devon Ice Cap has a larger measured mass balance in the world. The ice thickness of the White Glacier reaches or exceeds 300 meters. Scientists have studied this glacier since 1960 to understand glacier facies, which are different zones of a glacier. Protecting these sites is a modern priority. Because the fossil wood is easily damaged by erosion, Nunavut is considering creating a territorial park. This park might be named Napaaqtulik, which means "where there are trees."
