Another critical step in excavating the site is recording where things are found. Archaeologists spend a lot of time carefully measuring and plotting the positions of the artifacts that they discover at the site. From this information, they are later able to construct maps of the site and study the distributions of the artifacts. This helps in working out which artifacts were originally used together and what they were used for.

Once all of the information has been tabulated, and the artifacts have been analyzed in the laboratory, maps can be drawn, like the one below. This one shows the concentrations or clusters of artifacts in part of the Lums Pond site by the creek. From these maps, we can deduce the types of activity that may be represented by the artifacts. This map shows two main groups of artifacts. One consisted mainly of cobbles from the creeks that had been burned and broken in hot fires -- probably a cooking fire. The other group contained flakes of jasper chipped from stone tools as they were being made.
