Harrington method pipestem dating
Historical archaeologists date their sites using a variety of methods, each with its strengths and weaknesses.
Here’s a roadmap that explains how we dated the midden feature itself, its layers and phases, and developed the site chronology incorporating documented events found in the archaeological record. Historical archaeologists most commonly utilize documented changes in ceramic ware type and decoration to date layers, features, and archaeological sites.
The rest of this newsletter will focus on the prehistoric aspects of Thoroughfare Gap archeology, which is Johnson’s research interest.
However, Johnson will continue to provide preliminary assessments of historic results as appropriate.
As a result it is likely that any prehistoric occupations have not been disturbed by historic period activity.
This is supported by a discovery on September 3 that what was originally thought to be evidence of a shallow relic stream bed from when Broad Run was running across the feature, many thousands of years ago, was actually a prehistoric artifact.
By illuminating inconsistencies between material culture chronology and historically documented occupation periods, seemingly “erroneous” dates derived from uses of South’s mean ceramic date formula can be fully as valuable as is the technique’s more traditional application for dating.
Our paper formally recognizes and extends the use of the mean ceramic date approach as a tool for furthering the interpretation and explanation of human behavior in three categories: intrasite/ intrafeature, intersite/interfeature, intrasite/interfeature.
For example, if an archaeological site contains coins dated 1588, 1595, and others dated 1590 - 1625, the historic artifacts change over time and changes can be measured in years via a mathematical formula; pipe stem dating; SC Harrington- earliest founders of Early American historical archaeology; Lewis Binford: Regression Formula was based on Harrington’s observations of pipe stemshistorical event maps (Gettysburg and Boston Tea Party), Directory maps (pre phone books-name, address, occupation) atlas map (showed individual structures, Sonborn Fire Maps), Bird’s eye view maps (works of art, fairly accurate, reliable source of information), Specialized Map (plantation plans, boundaries of parcel, show location of buildings), Utility maps (show where pipes and sewers were located; 1840) Century Maps (large scale maps) State Mandate Maps (states required counties to conduct surveys and must show everything) County Maps (large wall maps, 1850-1880, sold by subscription) Atlas Maps (property ownership placed by real estate maps, continued to be published to 20Historic archaeology- deal with archaeology of the recent past, deals with shorter periods of time, can study known people, can study peoples whose general histories are known but whose daily lives are not well documented.
Mike Johnson, wrote up a progress report of the archaeological work that has been done at the Mill to date.
We’re excited to present the final section of the paper, Part 3 of his “Thoroughfare Gap Archaeology News” below (Click HERE for Part 1 and Click HERE for Part 2).
Currently, the excavation levels are below the historic artifact zone, with a possible exception of a disturbance in the northeast corner of Square 2 (N960E3476).
No evidence of a cellar or historic pits have been detected in the three test squares.
Figure 8 shows the large, water rolled boulder after it was cleaned off at the bottom of level 105 in Square 3.
