The Land of Taman Nasional Ujung Kulon

The highest points in the park are the 620 metre Gunung Honje, the Gunung Payung Range peaks of up to 500 metres and Panaitan Island's Gunung Raksa at 320 metres. In the central section of the Peninsula is a large region of wilderness known as the Telanca Plateau which reaches 140 metres above sea level, however most consist of low rolling terrain seldom morre that 50 metres above sea-level.

Surrounded by unusually warm warters, seldom varying from between 29o to 30o C. The coastlines of the park are moulded by the sea around them, battered by thee Indian Ocean, the long, sandy beaches of the south coast are backed by dunes, lagoons and forest broken by rocky outcrops - a wild and windswept shoreline.

The west coat's reef -lined shore has cliffs, promontories and towering sea-stacks along sand and boulder beaches of white sands and coral banks with islands, eestuaries, swamps and forest lined shores.

Along each coastline is a variety of seascapes which, in all their diveresity, offer a wide range of absorbing shoreline experiences.

GEOLOGY

The events that led to the formation of the land we know as Ujung Kulon began about 200 million years ago when what is now the Indian continent broke away from the super-continent of Goandwanaland. It collided with the Asian continent creating huge ripples acrross the earth's crust forming the snow-claad Himalayas along with Sumatra's mountaain rarnge, Bukit Barisan.

It is believed that the Ujung Kulon Peninsula and the Gunung Honje raange were at that time the southern end off the Bukit Barisan Range as Java and Sumatra were connected by a land-bridge. Then 20,000 to 15,000 years ago, the land-bridge collapsed to eventually form the Sunda Straits about 9,500 years ago.

However the period when the Straits was fformed is somewhat contradicted by aan intriguing account in an early Javanese chroniclee The Book of Kings. It states that in thee year 416 A.D. the mountain Kapi (Krakatau) "burst into pieces aand sunk into the deepest of the earth' and the seas flooded the land from Gunung Gede near Bogor to the mountain Raja Basa in southern Sumatraa. The chronicle concludes:- "After the waters subsided the mountain Kapi and the surrounding land becaame sea and the island of Java was divided into two parts".

It is curious fact that no sea straits between Sumatra and Java wa known before the 1100's by the far-ranging Chinese and Arabian traders and later European explorers.

Beneath the mountains and forest of Ujung Kulon, carved by the thousand of centuries of rain, wind and sea, are the foundations of the land - a young mountain system formed over the older strata of the Sunda Shelf.

Geoligacally, the Ujung Kulon Peninsula, Gunung Honje and PAnaitan Island are al part of this young Tertiary mountain system whilee the central part of Ujung Kulon is of older limestone formations wwhich have been covered by alluvial deposits in the north aand sand-stone in the south.

Much of the underlying rocks and early soils of the park are covered by volcanic ash, in places up to 1 metre deep, a legacy from the Krakatau erruptions.

The mountain ranges were all formed by the same folding event in the Mioocene 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 island of Krakatau to a major tectonic fault line to the south of Indonesia.
