How does climate affect the way archaeologists dig?

Dr. dig responds:
Climate is a very important factor that affects how an archaeologist carries out an excavation, but the fundamentals remain the same. Archaeologists dig square holes, make careful measurements, excavate according to the layers of deposit, and analyze artifacts the same way all over the world.

Climate, however, will affect things such as how long an excavation season will last, what protection the site needs from the regional climate - plastic covering for rainy climates, tents or roofs to shield an excavation and its diggers from a hot, desert sun, netting to keep mosquitoes and flies off diggers in tropical countries, and so on. The tools and recording materials an archaeologist will need to excavate a particular site will also in part be determined by climate. Some tropical climates are not kind to paper, for instance, which will disintegrate quickly from insects and humidity, so tags, labels, drawings and maps need to be carefully sealed and protected.
