Which peninsula in northwestern Russia lies between the Barents Sea and White Sea?

The Kola Peninsula in northwestern Russia lies between the Barents Sea and White Sea.

It is located almost entirely within Murmansk Oblast, north of the Arctic Circle. The Barents Sea borders it to the north and northeast, while the White Sea surrounds much of its southern and southeastern side. Its western boundary is commonly associated with the Kola Bay and the frontier with Finland and Norway.

The peninsula has a subarctic climate, tundra in the north, and taiga farther south. The Khibiny Mountains rise in its interior, and the region contains major deposits of apatite and other minerals. Murmansk, an important Arctic port, stands on the peninsula’s northwestern coast.

The Kola Peninsula is also known for the Kola Superdeep Borehole, drilled during the Soviet period near the town of Zapolyarny. It reached 12,262 meters in 1989, making it the deepest artificial point below Earth’s surface for many years.
