Photo and description

The ancient natural monument of the village of Girvas in Karelia is the remains of a volcano that originated more than 3 billion years ago. The volcano has not been active for a long time and nature has done a good job to erase the consequences of the volcano's activity, but now you can still see fossilized lava flows. Girvas volcano was discovered by geologist Svetov in the 60s of the XX century.

Girvas can be attributed to the Icelandic type volcanoes, it combines ancient sedimentary and younger volcanic rocks. After the hydroelectric power station was built here, the canyon was opened. Now you can see the texture of lava flows and fossilized volcanic "bombs" with gas voids inside. The lava tongue is very clearly visible near the coast. The lava layers around Girvas are about 100 m thick, and the area of the entire lava field is 1000 sq. Km, it consists of 17 smaller streams and runs from Girvas to Svatnavolok. The crater of the volcano was found relatively recently and, according to the assumptions of geologists, it is the oldest of the craters preserved on earth.
