Excavation is the mechanical removal of waste or contaminated soil from the subsurface. For example, the presence of an anomalous medieval pottery sherd in what was thought to be an Iron Age ditch feature could radically alter onsite thinking on the correct strategy for digging a site and save a lot of information being lost due to incorrect assumptions about the nature of the deposits which will be destroyed by the excavation process and in turn, limit the site's potential for revealing information for post-excavation specialists. The removed soil at an excavation site is also called ____________. Archaeological context refers to where an artifact or feature was found as well as what the artifact or feature was located near.

To mitigate this, highly accurate and precise digital methods can be used to record the excavation process and its results.[24]. EPA. "Dimensional analysis of behaviour & site structure: learning from an Eskimo hunting stand". If a material is waste, waste rules apply when it undergoes a recovery operation, such as preparation for reuse or recycling, or a disposal operation. You can specify conditions of storing and accessing cookies in your browser. The process involves the removal of wide and shallow layers of topsoil, rocks, sand, and other unwanted materials. Clean spoil may be used for land reclamation. It can also include the adding of media to the ground, such as sand, stone, concrete and soil. Excavating companies will use equipment to spread topsoil and other fill materials in a particular spot of land to create a smooth, even surface. After high quality digital data have been recorded, these data can then be shared over the internet for open access and use by the public and archaeological researchers. This is especially suited to the recovery of environmental data stored in organic material such as seeds and small bones. Spot dating also forms part of a confirmation process, of assessing the validity of the working hypothesis on the phasing of site during excavation.
