Two volcano summits and a World Heritage listing: Hawaii Volcanoes National Park

Background

Kilauea, which has just produced episode 55 of its Halemaumau eruption, stands inside Hawaii Volcanoes National Park, so the park itself is worth knowing.
The National Park Service says the park takes in the summits of two volcanoes, Kilauea and Mauna Loa.
It calls them two of the world's most active volcanoes.
The park lies in the state of Hawaii, with its postal address at Hawaii National Park.
Its land rises from sea level to 13,680 feet, so a visitor crosses several climate zones in one park.
That range of height and rainfall is why the park holds so many kinds of plants and animals.
The park is a designated International Biosphere Reserve.
It is also a UNESCO World Heritage Site.
