An important discovery of the underwater marine archeological finding is reported here. This is very old site known in India associated with the Hindu God Krishna. 22 Degree 31' 13.52 North and 69 Degree 19' 48.73" East, is India's most wanted and challenging site, which mainstream historians' don't like to speak or see. Almost hidden from the last 5000 years. This is Dwarika marine island in India. In the Marine discovery and Archeological finding this is the first experiment, where Udaipur Lake Palace in India was used to identify as tool for searching the lost Dwarika. This contains 3 chapters and one photographic appendix. The first chapter is devoted on the search of the Dwarika. The remaining two chapters are evidence which binded the discoverer that the submerged Dwarika is not a myth but a fact that Krishna and his Dwarika island both are existing. The ancient Indian literature says, Dwarika was an illuminating island. When search started in the Gulf of Cambay, the author used Udaipur Lake Palace as tool to record the impression of signal in the satellite. It was seen the 'purnima night' (full moon night), was giving more return signal of light in the night then in the day during the presence of sunlight. This pattern of signal what satellite was sensing any illuminating object during the night time in the sea, was major innovation behind this discovery. The book cover gives the illumination pattern of the ancient Dwarika. This discovery has revealed first time different types of water forts, port, water hydraulic system and artifacts with more than 45 photographs spread in that island. One major premise has also been photographed by the satellite in white building of crane bird shape. This is believed to be the palace of Krishna. This discovery has demolished the Aryan Invasion Theory in 1500 BC and Krishna has been established as the king of Mohenjodaro. This old site is in danger and about to extinguish if immediate relief and control measures are not adopted by the government. This needs immediate restoration and aid from the international communities to support the conservation work. The book is authored by Birendra K Jha. Who is a reputed author.
