23. USA, Hawaii Volcanoes National Park

It seems to be incredible when we think about 2 active volcanoes which are part of National Park, Hawaii Volcanoes National Park to be more specific. Card was sent by Alyssa, really nice Postcrosser I had chance to trade with. Park was established in 1916. As said before it encompasses two active volcanoes: Kīlauea, one of the world's most active volcanoes, and Mauna Loa, the world's most massive subaerial volcano. The park gives scientists insight into the birth of the Hawaiian Islands and ongoing studies into the processes of vulcanism. For visitors, the park offers dramatic volcanic landscapes as well as glimpses of rare flora and fauna. In recognition of its outstanding natural values, Hawaiʻi Volcanoes National Park was designated as an International Biosphere Reserve in 1980 and a World Heritage Site in 1987.
