The formation processes that produce the surface context studied through intensive pedestrian survey are really annoying. They hide things that you know MUST be there (like Late Roman material on a prominent coastal height overlooking a Roman to Late Roman settlement). They make visible things that have no rational explanation (like the famous one sherd of Classical black-slipped pottery on a lonesome hillside). Various formation processes scramble and smear and move and interrupt and complicate assemblages across the landscape and force survey archaeologists to keep stepping back and back and back until the picture comes into a kind of blurry focus. Outliers are noted, but major patterns become the basis for analysis.
This past week, I’ve been working on an article with Grace Erny on the houses of Chelmis in the Argolid which we are study as part of the Western Argolid Regional Proect. Grace is going to give a paper on our preliminary results at the annual Archaeological Institute of America meeting next week (check out a list of all the WARP papers here). These are “Early Modern” to “Modern” period houses around which we conducted intensive survey in 2016. To get a sense for the impact of the houses on the distribution of artifacts in their immediate vicinity, we did 10 m of very intensive documentation counting all the roof tiles, ceramic artifacts, and other objects around the houses. We grouped our survey into three units on each side: one of 2 m in width walked by a single walker and two of 4 m in width walked by 2 walks. These units produced largely consistent patter of a 65% percent drop off between the 2 m unit and the first 4 meter unit and then a 25% drop off between the first and the second 4 m unit.
Not every house produced this distribution, but it was consistent enough both at Chelmis and at the two other sites where we conducted intensive survey to qualify as a pattern. And this is worthy of note in a universe where the trickeration of formation processes often makes any small scale patterning of artifact densities in the landscape either rare or suspect.
Hoping that all your survey assemblages pattern predictably in the new year!
