ABSTRACT
There are many types of archaeological remains of every period. Upstanding remains are the most obvious but many others such as ancient settlements are to be found all over the countryside and underneath our towns and cities. Sites also vary enormously in their state of preservation and can range from well preserved wetland sites to others which are virtually unrecognizable because of the erosion that has occurred. They cannot all be investigated in the same way and different approaches must be adopted in the way sites are discovered or how further information about them may be obtained.
