ARCHEOLOGYSurveying in Africa is critical, but unless you have thecorrect equipment and trained archaeologists, the fieldwill be a difficult and time-consuming process.Archaeology surveying is the processof gathering information aboutthe past through excavation andsurveying. It can take a variety of forms andcan be either intensive or non-intrusive.Archaeology surveying can provide importantinformation about human activities duringthe past. It can be an important step beforearchaeological excavations take place.During archaeological field work in Africa,geophysical methods are increasingly used.Until recently, magnetic surveying was notwidely used in sub-Saharan regions. This newtechnique is now widely used in sub-Saharanarchaeology. In the Chad Basin, the Zilum siteis part of the Gajiganna Culture and datesback to 600-400 BC.Archaeology surveying is an important partof conservation efforts and can help preserveand protect African cultural heritage. Throughthis project, researchers will documentpreviously unknown archaeological andcultural heritage sites. They will focus onsites that are under threat from urban growth,conflicts, and infrastructural development.Researchers will receive in-country trainingto identify archaeological sites and maintaindatabase records.Surveys are important reconnaissance toolsin African archaeology, but the amount ofsurface research is still limited. This articlereviews the state of surface archaeologyin Southern Africa, reviews its role inlandscape archaeology, and considers Bower'smethodological concerns. It also presents acase study from the Tankwa Karoo region ofSouth Africa.Surveying in Africa is critical, but unless youhave the correct equipment and trainedarchaeologists, the field will be a difficultand time-consuming process. But if you havethe proper training and a keen eye, it willyield rewards. The benefits of conductingarchaeological surveys are significant andwell worth the effort. If you are interested inlearning more about archaeological surveysin Africa, here are some tips:The 2004 survey season established anextensive and diverse archaeological record.It identified previously undocumentedtell sites on floodplains. The data indicatethree distinct stages in the history of theregion's human settlement: the foragingphase, a lengthy period of cultivator-foragereconomies, and the second phase of smallscalefarming.An important consideration in archaeologicalsurveying is visibility. If visibility is good,researchers will use fieldwalking tosystematically walk through an area lookingfor artifacts and archaeological indicators.They will also take notes about thesurrounding environment at the time. Thismethod is most effective when the area is flatand has little vegetation. Because artifactsBut if you have theproper training anda keen eye, it willyield rewards. Thebenefits of conductingarchaeological surveysare significant andwell worth the efforttend to move to the surface of the soil,fieldwalking does not always detect them.Archaeology surveying methods varyconsiderably, but the basic principles ofall methods are the same. The methodof surveying must be appropriate for thearchaeological site and the site's location.Before deciding on the surveying method,archaeologists must first define thestudy area and become familiar with itsnatural characteristics. Another method ofarchaeological surveying is by using remotesensing techniques. These techniques allowarchaeologists to conduct subsurface testingwithout disturbing the surface. One techniqueuses a proton magnetometer to measurethe strength of the earth's magnetic field.Unscathed dirt registers a smooth plane whenthe device is placed on it. Disturbed dirt, suchas ditches, will alter the magnetic reading.The method is effective in detecting middens,ditches, and burned structures.Gedi Ruins, Kenya
