To the south from the Carpentaria Gulf there is seen extremely unusual weather phenomenon - Morning Glory of Carpentaria Gulf.
It happens (and rather often), that early in the morning above the surprised spectators "roll" over one or few roll clouds - long, low, narrow clouds resembling giant, up to 1,000 km long ropes. Elsewhere in the world this is very rare phenomenon but here it is frequent. This is the only place on Earth where this beautiful natural phenomenon can be predicted.
One of the tallest and certainly - some of the most beautiful falls in India are Nohkalikai Falls. Water here falls in a single plunge approximately 335 m high.
Weird things are happening some 70 - 100 kilometres downstream from the Vientiane - capital of Laos.

These mysterious sparkles are small, but sometimes they reach a size of a basketball.

This monument has been extensively excavated and a lot here has been rebuilt and reconstructed. Nevertheless this is magnificent and enigmatic monument of history.
