Haleakalā was originally part of Hawaii National Park along with the volcanoes of Mauna Loa and Kilauea on the island of Hawaiʻi, created in 1916. Hawaiʻi Volcanoes National Park was made into a separate national park in 1961. The park area was designated an International Biosphere Reserve in 1980. The name Haleakalā is Hawaiian for house of the sun. According to a local legend, the demigod Maui imprisoned the sun here in order to lengthen the day. The Hawaiian National Park Language Correction Act of 2000 was proposed to observe the Hawaiian spelling, but it did not become law.
