The Longest Natural Arch

The spectacular Landscape Arch in the Arches National Park in Utah, U.S.A., is the world's longest single naturally-formed arch. It is 89 m long and 32 m high. The Park contains more than a thousand natural arches, more than anywhere else in the world.
The area was once a basin below sea-level. It was flooded with sea water about 300 million years ago. A layer of salt was deposited at the bottom of the basin. Rocks and other debris collected on top and eventually reached a thickness of 1.6 km. The accummulated weight caused the rock to crack and collapse in places. Water seeped in and gradually eroded the softer rock to form arches.
The Park also has cave-like structures and heaps of rubble from collapsed arches. There are numerous 'windows' in the rock which will, in time, turn into arches.
One arch which is on the point of collapse is the Ribbon Arch which is 15 m long and only 6 cm wide and 30 cm deep at its narrowest point.

Dimdima is the Sanskrit word for ‘drumbeat’. In olden days, victory in battle was heralded by the beat of drums or any important news to be conveyed to the people used to be accompanied with drumbeats.
