There are two main differences between what we can see today from a satellite hovering over the east end of the Mediterranean Sea and what would have been seen thirty-five hundred years ago. First, Lake Huleh north of the sea of Galilee is nearly gone. Also called the waters of Merom, Lake Huleh has been steadily silting up for millennia. By modern times, it was mostly a swamp, and from 1950 to 1958 over 12,000 acres of it were drained to become farmland. The second thing we would notice is that the Dead Sea has shrunk. It is literally drying up and is probably half the size it was in Old Testament times.
