Listen up, archaeokids. Lets say you first excavate context A, writing "A" on all the find baggies. Then you kind of think that you've gone into a new context, so you start calling it context B and writing "B" on the baggies. Then you decide that B is actually not different enough from A to be treated usefully as a separate entity. This is completely OK. Just put in the field notes that A=B. 1/2
