Politics
You may be working with governments that are not democratic. They may think you ask too many questions. They may suspect you of trying to steal the artefacts. They may worry you’ll end up taking the glory if you discover something interesting.
Environment and climate
You could get snakes, scorpions or centipedes in your sleeping bag! You could be working in extreme weather, either cold and damp or very hot, which can lead to sunstroke, dehydration. You could get injured in a remote location miles away from hospitals and need to be airlifted to hospital by helicopter.
Infrastructure
There could be poor local infrastructure and services, e.g. airplanes that burst into flames, etc.
Preparation
You need loads of data before you go out; you need to do your research. Otherwise, you’ll be wasting your time.
