The park's 120.551 hectares are divided into 76.214 ha of land and
44.337 ha of surrounding reef and sea. It can roughly be separated into
three areas: the triangular shaped Ujung kulon Peninsula, the Gunung
Honje Range to the east of the peninsula's isthmus and the island of
Panaitan to the northwest. The highest points in the park are the 620
meters Gunung Honje, the Gunung Payung Range peaks of up to 500 meters
and Panaitan Island 's Gunung Raksa at 320 meters. In the central
section of the Peninsula is a large region of wilderness known as the
Talanca Plateau which reaches 140 meters above sea level, however most
consist of low rolling terrain seldom more than 50 meters above sea
level.
The park surrounded by unusually warm water, seldom varying
from between 29C to 30C. The coastlines of the park are molded by the
sea around them, battered by Indian Ocean; the long sandy beaches of the
south coast are backed by dunes, lagoons and forest broken by rocky
outcrops a wild and wind swept shore line.The west coast's reef-lined
shore has cliffs, promontories and towering sea-stacks along sand and
boulder beaches overhung by forest, creating the most spectacular
coastline in the park.On the north coast, the sheltered tropical straits
lap upon beaches of white sands and coral banks with islands,
estuaries, swamps and forest lined shores.Along each coastline is
variety of seascape which in all their diversity, offer a wide range of
absorbing shoreline experiences.
GEOLOGY
The even that led to formation of the land we as Ujung
kulon began about 200 years ago when what is now the Indian Continent
broke away from the super-continent Gondwanaland. It collided with the
Asian continent creating huge ripples across the earth's crust forming
the snow-clad Himalaya along with Sumatra's mountain range, Bukit
Barisan. It believed that the Ujung kulon Peninsula and the Gunung Honje
Range were at that time the southern end of Bukit Barisan Range as Java
and Sumatra were connected by a land-bridge. Then 20.000 to 15.000
years ago, the bridge collapsed to eventually form the Sunda Strait
about 9.500 years ago.
How ever, the period when the strait was
formed is somewhat contradicted by an intriguing account in an early
Javanese chronicle The Book of Kings. It states that in the year 416 AD
the mountain Kapi (Krakatau) burst into peaces and sunk into deepest of
the earth and the sea flooded the land from Gunung Gede near Bogor to
mountain Raja Basa in Southern Sumatra. The chronicle concludes: After
the waters subsided the mountain Kapi and surrounding land became sea
and the island of Java was divided into two parts.
It is a curious
fact that no sea straits between Sumatra and Java was known before
1.100's by the far ranging Chinese and Arabian traders and later
European explores.Beneath the mountains and forest of Ujung kulon,
carved by the thousands of centuries of rain, wind and sea, are
foundation of the land - a young mountain system formed over the older
strata of the Sunda Shelf. Geologically, the Ujung kulon Peninsula,
Gunung Honje Range and Panaitan Island are part of this young tertiary
mountain system while the central part of Ujungkulon is of older
limestone formations which have been covered by alluvial deposits in the
north and sandstone in the south. Much of underlying rocks and early
soils of the park are covered by volcanic ash, in places up to 1 meter
deep, a legacy from the Krakatau eruptions.
The mountain ranges were
all formed by the same folding event in the Miocene period creating
beneath the forest of the Gunung Honje Range an eastward tilting
mountain block. A reminder of this activity is a geological fault line
situated off the Tamanjaya coastline. It bisects the park beneath the
isthmus as it passes through the Sunda straits connecting the volcanic
islands of Krakatau to the major tectonic fault line to the south of
Indonesia
