[OC] As an amateur Archaeologist and professional GIS map maker, I find arrowheads for fun. I took my GPS data from arrowhead finds from the years 2000-2021 and plotted it. I then ran an interpolation tool where the computer predicts where I would be most likely to find more arrowheads (yellow-red)
