Wrangel Island

Wrangel Island is a cold place.

It sits in the Arctic Ocean. It is part of Russia.

The island has mountains and flat lands.

It is also very windy. Many birds live there too.

Long ago, woolly mammoths lived here. They lived there for a long time.

Now, they are gone.

Polar bears live on the island now.

They like to make dens there. Many seals and walruses live in the water too.

This island is a special place to study. People go there to learn about nature.

Wrangel Island is a large island in the Arctic Ocean.

It is part of Russia. The island sits between two seas. These are the Chukchi Sea and the East Siberian Sea.

The island has many different parts. There is a wide plain in the south. In the middle, there are low mountains. The highest peak is Gora Sovetskaya.

It is 2,138 meters tall. The north side also has a wide plain.

Life on the island is very special. Long ago, woolly mammoths lived here. They stayed on the island until 4,000 years ago.

Now, polar bears live there. They use the island to make dens. You can also find walruses and many kinds of birds.

The weather is very cold and windy. Most of the year, it is freezing. The summers are very short. There are only about two weeks without frost. Because it is so special, Russia protects the island. It is a place for science and nature.

Wrangel Island is a huge place in the Arctic Ocean.

It sits within the Chukotka Autonomous Okrug of Russia. The island is located between the Chukchi Sea and the East Siberian Sea. It is the 92nd-largest island in the whole world. Some people say it is about the same size as the island of Crete. The island is also very special because it sits on the 180th meridian. This line is where the International Date Line moves slightly to the east. This helps the island stay on the same day as the rest of Russia.

The land on the island has many different shapes. There is a wide plain along the southern coast. In the middle, there is a belt of low mountains.

The highest part of these mountains is the Tsentral'nye Mountain Range. The highest peak is called Gora Sovetskaya. It reaches an elevation of 2,138 meters above sea level. The northern part of the island is also a wide plain. Even though it is very high and far north, the island does not have glaciers.

A long time ago, this island was very famous for its animals. It was the last place where woolly mammoths lived.

Scientists used radiocarbon dating to study their bones. They found that mammoths lived here until about 4,000 years ago. This was during the time of ancient Egypt and the Bronze Age. While mammoths died out elsewhere, 500 to 1,000 mammoths stayed isolated here. Today, the island is a home for many other animals.

Polar bears use the island to make many dens. You can also find walruses, seals, and Arctic foxes there.

Captain Thomas Long gave the island its name. He named it after Baron Ferdinand von Wrangel. The Baron was an explorer and an Admiral in the Russian Navy. Interestingly, the Baron never actually visited the island himself. He only knew about it because he saw many birds flying north. He searched for the island during his expedition from 1823 to 1824. He did not find it during that trip. Later, the island became a very important place for science and protection.

Because the island is so special, it is a protected nature sanctuary. Russia calls it a "zapovednik," which means a strict nature reserve. This means almost no humans can live there. Only a few people work on the island for science. In 2003, there were four rangers living there all year. About 12 scientists also visit during the summer months. The island is also part of the UNESCO World Heritage List. This list helps protect the most important natural places on Earth.

Wrangel Island is a significant Arctic landmass located in the Chukotka Autonomous Okrug of Russia.

It serves as a major landmark separating the East Siberian Sea from the Chukchi Sea. The island is the 92nd-largest island globally and is roughly comparable in size to Crete. Its location is unique because it sits astride the 180th meridian. This placement causes the International Date Line to displace eastwards at this latitude. This adjustment ensures the island and the nearby Chukchi Peninsula remain on the same day as the rest of Russia. The small, rocky Herald Island lies just to the east of this large territory.

The island's physical structure consists of three distinct topographical zones. A wide southern coastal plain forms the bottom of the island. Above this lies a central belt of low-relief mountains that runs from east to west. The highest elevations are found within the Tsentral'nye Mountain Range. The northern section of the island is another wide coastal plain. The highest peak is Gora Sovetskaya, which reaches 2,138 meters above mean sea level. Most other mountains on the island reach heights just over 1,000 meters. Despite its high latitude and mountainous terrain, the island is not glaciated.

Geologically, the island is composed of various complex rock layers. These include folded, faulted, and metamorphosed volcanic, intrusive, and sedimentary rocks. The oldest layers are Precambrian rocks, which are about 500 meters thick. These consist of sericite and chlorite slate and schist. These ancient layers are intruded by granite and other types of rock. Overlying these are strata of Upper Silurian to Lower Carboniferous sandstone and siltstone. Up to 1,000 meters of Carboniferous to Permian limestone also exist here. These limestone layers often contain crinoid plates. The topmost layer consists of Triassic clayey quartzose turbidites.

The history of the island's naming is tied to an explorer who never saw it. Captain Thomas Long named the land after Baron Ferdinand von Wrangel. The Baron was a Baltic German explorer and an Admiral in the Imperial Russian Navy. He noticed large swarms of birds flying north and suspected an island existed. He searched for it during his Kolymskaya expedition between 1823 and 1824. However, he failed to locate the island during that specific voyage.

Wrangel Island is world-famous for its prehistoric connection to the woolly mammoth. While mammoths disappeared from mainland Eurasia and North America around 10,000 years ago, a small group survived here. Approximately 500 to 1,000 mammoths remained isolated on the island. They continued to live there for another 6,000 years. Radiocarbon dating shows they persisted until around 2500–2000 BC. This means they lived while the fourth dynasty of Ancient Egypt was active.

This makes Wrangel Island the last generally accepted habitat for the species.

Today, the island is a vital sanctuary for Arctic biodiversity. It is a "zapovednik," which is a Russian term for a strict nature reserve. This status provides the highest level of protection and limits human activity to scientific research. In 1976, the island and its surrounding waters were classified this way. The Chukotka Regional government extended these marine protections offshore in 1999. Because of its unique ecology, it joined the UNESCO World Heritage List in 2004.

The island hosts the highest density of polar bear dens in the world. It also supports walruses, bearded seals, and ringed seals.

The flora and fauna of the island are remarkably diverse for the Arctic. The island contains 417 species of plants. This is double the amount found in any other Arctic tundra territory of similar size. Many birds use the island as a breeding ground, including various species of geese and snowy owls.

The island also features a complex water system. There are approximately 1,400 rivers and about 900 shallow lakes. These waters have very high oxygen content and low salinity. This unique environment makes Wrangel Island a critical piece of the global Arctic ecosystem.
