aug 26, 2348 BC - The Flood Waters Rose to their Highest Level

Description:

The water rose to its highest level (covering the whole earth) sometime between the 40th and 150th day, and the end of these 150 days was the seventeenth day of the seventh month. The Ark rested on the mountains of Ararat. On the 150th day, the springs of the great deep were shut off, and the rain from above ceased, and the water began continually receding.
