There just aren’t that many archaeologists, and, unlike plumbers or electricians, responding to emergency calls isn’t a normal part of their work. So when multiple discoveries overlap, the delays can become severe. And those delays can in turn delay other work. The result is a chain reaction of setbacks, like a line of cars sliding into one another on an icy street. In this way, what starts as one minor fender bender becomes gridlock capable of derailing the whole project.
