Dwaraka

Seven miles off shore,while scanning the sea floor with ( again! ) side scan sonar, at adepth of 170 feet, they started picking up images that were both regular and repetitive - straight lines forming grids . It was something significant, because itcovered five square miles of the floor.
The Indian government immediately dispatched exploratory and survey teams to investigate. Underwater work at the site is very difficult and dangerous because there are very powerful cross currents in that region.
Even so, they were able to locate many of the features that had produced the grid shaped images on their sonar screens. Long stone walls are clearly visible on the sea floor, obviously made of cut, shaped and stacked stones.
Two distinct cities were located, both situated on the banks of a former riverbed. The cities were both large and well-formed. The grid maps of their streets are reminiscent of Mohenjo-Daro, Harrapa and the other cities of the Indus Valley culture.
Even more exciting, they have been able to bring up dozens of artifacts and evidences of human habitation. Objects of stone, pottery, metal and wood have been retrieved. There have even been fragments of bone found.
