When a projectile point is found in close proximity to the fire pit or hearth, it is likely that the projectile point is approximately the same age as the charcoal from the fire pit or hearth. These bits of charcoal are sent to a laboratory with equipment that can detect chemical changes within the sample, which in turn measures how old the charcoal sample is. Most often, these lines of evidence result from carbon dating.Ĭarbon dates most often come from archaeologists unearthing a fire pit or hearth and carefully collecting pieces of charcoal. Much of this information is determined by association, but these associations are almost always based on multiple lines of evidence which reached the same (or very similar) results. Projectile points can provide quite a bit of information about a person or group of people, such as the time frame they lived in, where they traveled, and some of the things they ate. Artifacts like these are referred to as projectile points. A typical goal for the archaeological field technicians assisting lead investigators is to find interesting artifacts like spear points and arrowheads.

The goal of the lead investigators is always to identify cultural resources like archaeological sites and collect as much data as possible to make informed decisions about how to best manage those resources.

This projectile point was found on Fort McCoy during an archaeological dig in 2016. A projectile point for a spear shaft, made of Prairie du Chien chert for, is shown.
