UNESCO site Hawaii Volcanoes National Park, sent by Julia in Hawaii. Kilauea is one of the world's most active volcanoes.

UNESCO - Kamchatka volcanoes, Russia

What an amazing landscape.  This Kamchatka Volcano card from Russia is a great addition to my UNESCO collection.

UNESCO Kamchatka volcano

Another great addition to my UNESCO collection.   This one comes from a swap with Atlantidochka on the postcrossing forums.  A great mix of stamps too.

"This is one of the most outstanding volcanic regions in the world, with a high density of active volcanoes, a variety of types, and a wide range of related features. The six sites included in the serial designation group together the majority of volcanic features of the Kamchatka peninsula. The interplay of active volcanoes and glaciers forms a dynamic landscape of great beauty. The sites contain great species diversity, including the world's largest known variety of salmonoid fish and exceptional concentrations of sea otter, brown bear and Stellar's sea eagle."
