Mauna Kea is a dormant volcano that stands nearly 14,000 feet above sea level. The highest peak in Hawaii, it is a sacred place for native Hawaiians. It is also a sought-after location for astronomical observatories. There are currently 13 telescopes on the mountain, and there are plans for a fourteenth.
The proposed telescope, called the "Thirty Meter Telescope," would be massive and it’s the focus of intense controversy. Some native Hawaiians are strongly opposed to the project for spiritual, cultural, and environmental reasons. There have been years of protests.
