Because of the extreme altitude of Mauna Kea, astronomers and technicians must acclimatize and live at an intermediate altitude. The Onizuka Center for International Astronomy (also known as Hale Pohaku - Hawaiian for "Stone House") has living facilities for up to 72 people working at the summit, as well as a visitor center and other support buildings. This photograph is partially obscured by drifting smoke from a distant fire - the 1998 winter was very dry, with drought conditions and extreme fire danger on the Island of Hawaii.
Ellison Onizuka was a local Kona boy with big dreams that landed him a spot as a crew member of the ill-fated space shuttle Challenger. The center is dedicated to his memory. The center is at the altitude limit for young children, pregnant women, elderly individuals, and people with respiratory problems. There are free stargazing programs on the summit Friday through Sunday, 7:00 to 10:00 p.m. You must have a four wheel-drive vehicle to get up here.
