Hello
and welcome back to our blog. In this
post we make our second visit to one of the big 59 National Parks, and our
first visit to the nation’s 50th State as we travel to Hawaii Volcanoes National
Park!

BACKGROUND:
The Hawaiian
Islands are the product of millions of years of geological activity. Located in the middle of the Pacific Ocean,
the islands were created through volcanic eruptions as the Pacific tectonic
plate gradually moved over what is known as a ‘hot spot’, a weak area in the
Earth’s crust. At these hot spots,
volcanic eruptions are frequent, and in the case of Hawaii, created the entire
island chain as the hot spot built up volcano after volcano. The hot spot in the
Pacific plate currently resides under the largest of the Hawaiian Islands, the
namesake of the island chain, better known simply as the Big Island.
The geologic
properties of the Pacific hot spot have led Hawaii to be the home of the world’s
most active volcanoes, in particular Kilauea, which has been erupting
continuously since 1983, and at the time of this writing, is erupting in two
places at the same time. The constant
eruptions on the island led the Ancient Native Hawaiians to believe it was home to the
Polynesian fire goddess Pele, and the volcanoes held a deep religious
significance. The lava spewed forth from
the volcanoes continues to add rock and landmass to the island of Hawaii every
year.

To
recognize the uniqueness of the volcanic landscape, the area surrounding
Kilauea, the larger Mauna Loa volcano, and Haleakala on the island of Maui were
designated Hawaii National Park in 1916.
Later in 1961, Haleakala was split off to create its own National Park,
with the park lands on the Big Island re-designated Hawaii Volcanoes National
Park.
THE PARK:
Hawaii
Volcanoes National Park surrounds the peak of Kilauea volcano and a large area
down its southwest flank extending to the island’s coastline. The park also stretches up over the top of
Mount Mauna Loa, the second tallest mountain on the island and largest mountain
landmass in the world. A section of
tropical rain forest near the volcanoes is also preserved as a wilderness.

The
Park is centered on the summit of Kilauea volcano. At the summit is the volcano’s primary crater,
several miles wide, at the center of which is a further two craters, the
smallest of these two contains a lake of lava in constant eruption since 2008. There are two visitor centers on the crater
rim, the primary visitor center near the park entrance, and the Thomas Jagger
Museum which overlooks the crater and is home to an observatory of the U.S.
Geological Survey. A road once circled
the entirety of Kilauea crater, but the southern half of the road and a zone downwind of the
summit has been closed for the duration of the current eruption due to safety
concerns. Also around the summit crater
is the Volcano House, a hotel lodge with views of Kilauea, and the Kilauea
Military Camp, a recreation area reserved for Military personnel.

To
the east is Kilauea’s smaller neighbor, Kilauea Iki crater, and the Thurston
Lava Tube, a cave cut through the rock by a lava flow. From there, meandering southeast, is Chain of
Craters Road, which passes by a series of craters left by various eruptions in
Kilauea’s East Rift Zone. The road
continues across a vast lava field and down a massive escarpment toward the
ocean, terminating on the coast at the famed rock formation called the Holei
Sea Arch. The road once connected with a
seaside highway, but the road was cut by lava flows in 1987 and remained closed
ever since. The source of these lava
flows is Pu’u’O’o, a volcanic cone which has been erupting continuously since
1983, the world’s longest recorded eruption.

TRAVEL TIPS:
Hawaii
Volcanoes National Park is a roughly half-hour drive south from the city of
Hilo, the island of Hawaii’s largest population center, and an hour and a half
from Kailua-Kona on the island’s west coast. The park is open twenty-four hours a day
year-round including holidays. The main
visitor center is open from 9am to 5pm, and the Jagger Museum from 10am to 8pm.
How visitors
explore Hawaii Volcanoes National Park will be a matter of personal
preference. It is recommended that
visitors budget an entire day to see both visitor centers and the length of
Chain of Craters Road. Nighttime viewing
of Kilauea crater from the Jagger Museum is a popular attraction, though
parking at the museum may be restricted necessitating a hike from other nearby
parking lots. There are similar parking
restrictions at the Thurston Lava Tube.
There are restaurants within the Volcano House open to the public for
lunch and dinner.

While it is prohibited to visit
the Pu’u’O’o Lava cone on foot, it can be seen via helicopter rides, and the lava
flows from this peak can be seen up close, however a great deal of hiking will
likely be necessary to find an active flow (as one Park Ranger told us, “If the
lava doesn’t kill you the hike will”). The
park has two established campgrounds.
The southern area of the park contains several sites for backcountry
camping. Mount Mauna Loa, at over 13,000
feet in height, can also be climbed but only by prepared and experienced climbers. Climate conditions at Kilauea Crater may at times also be moderately chilly. Visitors are advised to take heed of all
warning signs due to the inherent danger of the terrain.
There are gift shops located in
both visitor centers. The primary
visitor center has a short film while the Jagger museum displays feeds of
recent seismic data from the volcano. Some
areas of the Park are handicapped accessible, however most trails are not. Passport stamps can be found at the primary
visitor center and the Jagger Museum.

|
The area known as Sulphur Banks (note British style spelling), created by sulfur vents from deep within the volcano. |
|
A dangerous example of what happens when visitors do not heed warning signs. This vent at Sulphur Banks was created when a visitor stepped off the boardwalk and broke through the unstable ground, resulting in serious burns. |
