Camps were different depending on the circumstances. If a large body of men (corps size) were on the march, they camped where they stopped. You can find references to campsites in the mud, swamp or fields. If it were a pickett post or simi-permenant camp, the campsite would be chosen with the following in mind: Water, access to pickett posts, if they may be in view of the opposing forces, the camp may be in a valley. If it was winter the camp would be on the south side of the hills, seldom on top of a hill since the wind would be cold. If it was summer they would seek the shade. They camped in excellent locations and some god-forsaken ones. About the only thing you can look for is old bricks scattered around. If the land has not been disturbed look for fire pits and hut depressions. In fields you can find the bricks and maybe broken period glass. There may be no trace at all until you turn on your detector. In most all cases you will find someone has been there before you. It's that undiscovered camp which keeps us all looking and once and a while someone still finds one.
