A good guess would be that one or more glacial lakes in the mountains broke ice melted by a very warm deluge and together local natural elements combined to deliver one of large floods in the area. Archeologists have found several candidate flood layers that are much thicker than ordinary seasonal flood layers. However, without a precise date on Noah's flood, it is difficult to tell which flood layer was laid down by his flood.
