Looks like someone dug in a grid setup, and each artifact is plotted on the grid as to exactly where it was found. The finder has indicated some of the types found, and what material they are made of. For instance, #12 is likely quartzite Guilford, #9 is indicating rhyolite Morrow Mountain type 1(MMI), Kirk CN= Kirk Corner Notch, rhy stands for rhyolite.
The numbers on the grid are measurements pinpointing location within the grid. The numbers to the right of the notations identifying types and material are indicating how far down they were in the dirt.
Qtz=quartz. Qtze=quartzite. Cryqtz=crystal quartz.
On the piece of paper that shows outlines of the points, #7, qtzMM2= quartz Morrow Mountain type 2. There are two styles of Morrow Mountain point, denoted in the literature as type I and type 2.
The collection is from the Nottoway River, Virginia, an area rich in artifacts. Rhyolite, quartz, and quartzite are all common lithic materials for that area.
