List of Slides for Hawaii NP
Island of Hawaii
- A blocky aa lava flow advances slowly but
inescapably across the landscape in 1973.
- Pahoehoe lava, erupted in 1972, has a smooth,
ropy surface.
- Pahoehoe and aa lava flows drape a fault
scarp, remnant of the eruptions from 1969 - 1974 at Holea Pali.
- Another aa lava flow from the 1986 eruption of Kilauea blocks
a highway near Kapa ahu.
- This truck will never drive again!
- A lava flow from 1971 covers older cinders
and blocks, along the southwest rift zone.
- Lava flows devastate neighborhoods on the flanks
of Kilauea.
- The "fire pit", or active
crater, of Halemaumau in Kilauea caldera sometimes holds a lake of
bubbling, glowing lava.
- The side of Halemaumau Crater has collapsed
due to mass wasting. Mineral encrustations grow around the vents of fumaroles,
marked by rising steam.
- In 1959, a spectacular eruption formed Pu'u
Pua'i Cone in Kilauea Iki, a large pit crater near the caldera of Kilauea
Volcano.
- Devastation Trail leads to Pu'u
Pua'i Cinder Cone.
- Thurston Lava Tube, on the east side of
Kilauea, acted as a large pipe (~ 20 feet in diameter) to convey lava downslope
far from the vent.
- The outer crust of a lava tube insulates the molten rock inside, so
that it can continue to flow long distances. Later, the empty
tube remains as a tunnel.
- The famous black-sand beach at Kaimu
formed from weathered basalt.
- Mauna Loa Volcano rises 13679 feet above
sea level.
- Consequently, it even receives snow in the
winter, although it stands within the tropics!
- Pit craters line up in the caldera
of Mauna Loa. Mauna Kea, active 3000 years age, is visible in the distance.
- Weathered volcanic rocks provide fertile soil, as shown by the lush
vegetation of the Botanical Gardens
at Hilo.
