Field walking is a process of reviewing and sampling the archaeological potential of a site. In general, the Muskham Vale Heritage Group will be using 10m transects (spacings) to walk across a field looking for artefacts 1m either side of the walker. The best time for this activity is after the field has had time to weather a little following ploughing and the preparation of a seedbed. Sometimes, field walking is done soon after a crop is sowed. By analysis of the finds, and careful plotting, the field scatter of artefacts can be assessed. This may lead to further work, such as geophysical surveying, or even a trial excavation.
