The Gamburtsev Mountains are a subglacial mountain range located in Antarctica, specifically beneath the East Antarctic Ice Sheet. They were discovered in the 1950s during a Soviet expedition and are believed to be about 250 million years old. The mountains stretch approximately 1,200 kilometers (750 miles) and are covered by thick ice, making them difficult to study. These mountains play a crucial role in understanding the geology of Antarctica and the dynamics of ice sheets. The Gamburtsev Mountains are thought to influence the flow of ice above them, affecting global sea levels. Their unique structure provides insights into the continent's geological history and climate changes over millions of years.
