Igneous Rocks Aerion O'Kelley

Igneous rock is formed from magma, so what better place to find some than a trip to Mt Avachinskaya & Mt Koryakskaya, twin volcanoes on the Kamchatka peninsula in far-east Russia:

 There are a wealth of archeological and geological "gold mines" here, with samples of obsidian being almost around every corner. Obsidian tools from native peoples are found on the peninsula, and natural sources of obsidian are still all around.

Obsidian is an igneous rock and is even sometimes used in modern medicine or cosmetic surgery, as the edge can be much sharper than even surgical steel, reducing scarring and trauma. It also can be used as an alternative surgical implement if there is an allergy to steel (Shadbolt, 2015). Taking the trip to these volcanoes and seeing the tools early man developed from their natural environment was very educational.
