The only description that I know of is in the Old Testament in the Book of Exodus. My Sunday School teacher's husband had an uncle who was an archeaologist. In his lifetime he tried to figure out what happend to The Ark. His theory was that the ancient Egyptians took the ark out of Solomon's temple and took it back to Egypt and buried it in the sand. No one knows where the Ark could have gone.
Archaeology is full of surprises.
We will never know where a mystery such as the Ark might turn up, if it ever will.
