In archaeology, your coastline is architecture. Things get dangerous if you do not know what is going on around you. You might be tempted to dig deeper and faster, destroying important clues. Always work from the known to the unknown. A wall that exits one square, you know continues in the next.
Nothing can replace good fortune and luck.
A similar thing happened at our site last year when a worker's foot broke through the sealed entry of our hidden underground chamber. Decisions on where to dig are always prioritized. Each decision overlaps with questions of time, money and importance and usually involves detailed negotiations. There are over 740, five meter squares that cover the Monastery of John the Little alone. One becomes familiar with what to expect and defines buildings by moving from known architectural structures into unknown areas.
