Chapter 3 - Surveying the Site and the Soil

INFORMATION  ABOUT  ARCHAEOLOGY

An archaeologist who has received a licence will usually do a survey of the area to begin work on the site.

A survey could be just a walk over the site to see if there are remains or clues visible.  Surveys could include the use of technology like ground penetrating radar, resistivity or GPS.

Often, archaeologists will dig small test pits, about 50 cm. square, or even trenches of several metres length to learn:

-what the soil is like at the site and what layers - or strata - it forms,
-what kinds of artifacts the site may contain,
-which areas in the site will probably answer the research questions.

The soil is important to archeologists because artifacts are found in the soil.  If the archaeologist understands about the soil - how old it is, how it was formed, what chemicals it contains - this will help the archaeologist understand the artifacts.  Soil layers will be described and drawn in the survey notes.

The site will be mapped during a survey, including pits or trenches made.  The mapping could be done manually with a tape measure or with technical equipment like a theodolite or GPS system.  The site is located on an NTS map, using the co-ordinate system of numbers for these national maps.

The archaeologist will consider the information from the survey to decide:

-if or where the research on the site should take place,
-where should the point be placed on the site from which everything will be measured,
-where should the soil that is moved be placed (so it doesn't hide or cover something),
-how will the soil have affected the artifacts and site,
-how would it be best to investigate the site?

QUESTIONS

1.  Name three different ways an archaeologist could survey a site.

2.  What types of technology could an archaeologist use during a survey?

3.  Why is information about soil important to an archaeologist?

4.  Name some decisions an archaeologist makes based upon a survey.

GOALS

to examine soil science in relation to archaeology
to introduce how information is used for decision making in archaeology

OBJECTIVES

Knowledge
-record appropriate descriptors for soil (i.e. vocabulary)
-note the terminology used in soil stratigraphic profiles

Skills
-write descriptions (of soil)
-classify descriptors
-analyse information to assist with decision making
-use soil layers to note relative dating
-note the terminology used in soil stratigraphic profiles

Attitudes
-demonstrate the need to integrate scientific and geographic knowledge and skills (in archaeological work)

VOCABULARY


GPS         
-Global Positioning System - a technological system that uses satellites and map co-ordinates to record locations on maps

NTS           
-National Topographic Survey - the agency that produces topographic maps (showing physical and manmade features of the Earth - like hills or railway tracks) for the government

radar         
-a machine that uses the reflection of electrical waves to note the location of and give pictures of objects in the ground

stratum     
-(the plural is strata) a layer, usually of soil in archaeology

survey      
-(verb) to look over an area to see what archaeological evidence is there
-(verb) to map an area using surveying equipment
-(noun) the first test of an area to note the archaeological evidence there

SUGGESTED  LESSONS


Junior
Intermediate
Extension

Divide the class into groups.  Provide each group with a cupful of soil. (If soil is unavailable, a sheet of brown paper could be used.) Each group should have the same type of soil or sand.

Students should describe the soil under the headings of each of the five senses (sight, sound, touch, smell, taste).

The observations should be recorded.


Each group should present its findings.  These should be recorded by the teacher to synthesize them for the class as a whole e.g. on a chart.


The class should discuss:

1) were different terms used to describe the same thing e.g. colour;

2) what advantages or disadvantages there would be to use standard descriptions for something like colour.

The class should vote upon or create a standard set of descriptors for the soil.  Each group could be in charge of one sense or description e.g. smell, hardness, colour, etc.
Divide the class into groups.  Provide each group with a cupful of soil.  Each group should have the same type of soil or sand.

Provide each group with the soil description chart and information from this book, also a colour key system such as  coded point chip samples in soil colours.

Using the information provided, and correct terminology from it, students should complete the chart to describe the soil.

Each group should present its findings.  Record these for the class.

The class should discuss how using scientific terminology for soil descriptions would be useful for archaeologists.
Divide the class into groups.  Provide each group with:
1) a copy of the soil profile of the hypothetical site from this publication,
2) a map of the test trenches from that site in this publication,
3) the photograph of the building interior from this publication.

Each group should assume the role of the direction of the archaeological research at the site.

Based upon the soil profile and test trenches, each group should decide:
a) where on the site it would be best to look for remains of the building pictured,
b) which objects from the picture are likely to be located, based on the soil types.



EVALUATIVE  STRATEGIES


Junior
Intermediate
Extension
Present each group with a cup of soil which is in layers (or a drawing, if soil is unavailable). Using the standard descriptors created during class discussion, each group should describe the individual layers of the soil in its sample.

During presentation, groups may self-evaluate by noting whether their description is the same as the others using the class "standard".

Provide each group with the soil profile from the hypothetical site in this publication.

Using the soil profile and the descriptors from the above, students should continue the notes for the site report - field notes - begun in Chapter 1. In this entry, students should describe the soil on the site and how this information is important to the research.

Students in groups, pairs or individually may create a scientific experiment to test the rate and effects of decay upon artifacts such as those pictured in the photograph in this publication.  Students should include the following variables:

-organic and inorganic artifacts,
-different soil types e.g. topsoil, sand, subsoil.

The results of this experiment may be used to revise the research strategy from the lesson above.

DISCUSSION

Junior, Intermediate, Extension
By removing soil and artifacts, archaeology destroys the site it investigates.  Should archaeologists today continue to dig into soil to look for information, or leave sites buried until better technology is available to find out about the past without destroying sites?  Why/Why not?
