Mauna Kea Timeline

Disclaimer: THIS TIMELINE DOES NOT PURPORT TO BE A COMPREHENSIVE ACCOUNTING OF ALL EVENTS RELATED TO THE MISMANAGEMENT OR PROTECTION OF MAUNA KEA. The specific events called out in this timeline are relevant to OHA’s history and its current litigation regarding the mismanagement and protection of Mauna Kea.
  • 1893 – Illegal overthrow of the Hawaiian Kingdom
  • 1898 – Hawaiʻi is annexed by the U.S. Congress and 1.8 million acres of Hawaiian government and crown lands (i.e., “ceded” lands) are transferred to the United States as a “special trust.”
  • 1959 – As a condition of statehood, the U.S. Congress transferred most of the ceded lands to the newly formed State of Hawaiʻi with the stipulation that they would be held by the state as a public trust for five specific purposes – one of which is the betterment of the conditions of Native Hawaiians. Mauna Kea is part of the ceded lands trust and was designated by the state as a conservation district under the management of the Department of Land and Natural Resources (DLNR).
  • 1964 – The University of Hawaiʻi (UH) identifies Mauna Kea as possessing exceptional conditions for astronomy.
  • 1968 – 13,321 acres of ceded land at the summit of Mauna Kea is leased to UH by the state’s Board of Land and Natural Resources (BLNR) for a period of 65 years, from Jan. 1, 1968 to Dec. 31, 2033. The general lease executed between them allows UH to enter into sublease agreements. Over the next 20 years, six telescopes are built without proper permits.
  • 1974 – UH enters into a sublease with the National Aeronautics and Space Administration (NASA) for a rental fee of $1 for the entire 60-year lease period. It expires in December 2033, as do nearly all subsequent subleases.
  • 1975 – UH enters into a sublease with Canada-France-Hawaiʻi Telescope Corporation (CFHTC). No rent is charged.
  • 1976 – UH enters into a sublease with the Science Research Council (SRC). In lieu of rent, UH receives 15% of the observing time.
  • 1978 – (September) UH enters into a second sublease with SRC. In lieu of rent, UH again receives 15% of the observing time.
  • 1978 – (September) The Office of Hawaiian Affairs (OHA) is created and charged with managing 20% of proceeds derived from the ceded lands trust during a constitutional convention, thus clarifying the state’s trust obligation to Native Hawaiians.

  • 1995 – UH enters into a sublease with the Smithsonian Institution for an annual rental fee of $1.
  • 1998 – The first legislature-ordered audit report on the managment of Mauna Kea by BLNR and UH is issued. It (and three subsequent reports) found serious management defects.
  • 1999 – There are now 24 telescope structures on Mauna Kea, and infrastructure for 12 more. NASA and UH propose to build another four to six telescopes, finding no significant impact to Mauna Kea based on a short environmental assessment (EA).
  • 1999 – A second general lease for Mauna Kea is executed between BLNR and UH in combination with the first lease extending UH control of the summit through Feb. 27, 2041.

National Science Foundation Section 106 Process

The National Science Foundation (NSF) is considering investment in the construction and operation of the Thirty Meter Telescope (TMT). Section 106 of the National Historic Preservation Act (NHPA) requires federal agencies to identify and assess the effects any project, activity, or program funded in whole or in part by a federal agency may have on historic properties. Each federal agency must consider public views and concerns about historic preservation issues.

Right now, NSF is identifying consulting parties to engage with during the Section 106 consultation process under the NHPA. NSF anticipates that Section 106 meetings will be held during the first half of 2024.

There are four roles (categories) identified by NSF:

  • Native Hawaiian Organizations that attribute religious/cultural significance to land potentially impacted by TMT.
  • Representatives of local government with jurisdiction in the area affected by TMT.
  • Individuals/organizations with a vested interest in TMT due to legal, economic, or historical property concerns.
  • Applicants for federal funding related to the TMT project.
