AVON VALLEY ARCHAEOLOGICAL SOCIETY IS A REGISTERED CHARITY NO. 289516

2017

6th September 2017:  The Everyday life of the New Forest cottager in the 19th century
Speaker: Mr Stephen Ings

4th October 2017:  Shedding New Light on the New Forest
Speaker:  Lawrence Shaw, Archaeological Officer, New Forest National Park Authority

This talk will bring us up to date with the latest findings from a project using Lidar data to enhance our knowledge of archaeological sites within the New Forest.

1st November 2017: “Ancient Britons to Anglo-Saxons”
Speaker: Mr. Jim Barber

6th December 2017: “Three hundred miles in the footsteps of Vespasian – Recent work at Lake Farm legionary fortress.”
Speaker: Paul Cheetham, Senior Lecturer in Archaeological Science, Bournemouth University

The talk will discuss how the recent work has changed our understanding of the relationship of the fortress at Lake Farm to the Roman port at Hamworthy and its consequences for our understanding of the geography of Roman Britain in the south-west.

Events

As well as a high quality Winter lecture and meeting series (see the separate Meetings page), other events are arranged for members throughout the year.

Upcoming events are listed on the Upcoming Events page.  Examples of the types of events arranged by AVAS are described below.

Social Events

A number of social events are organised throughout the year, reaching their pinnacle at the annual barbeque in July, normally held at an idyllic spot next to the River Avon.

Field Visits

A number of field visits have been arranged for AVAS members.  One example is the visit to a late Roman site revealed by gravel extraction near Ringwood, as shown below.

A field trip is planned for Clearbury hillfort to examine the earthwork remains and contribute to a national survey of hillforts.

Fieldwork

AVAS members can get involved in a range of fieldwork, generally carried out within the valley of the Hampshire Avon.  Most people associate archaeological fieldwork with excavation, but archaeologists use a whole range of different techniques to investigate archaeological remains.

Some of the techniques employed by AVAS members are described below.  You can also read about fieldwork that has been undertaken on the AVAS Blog.

Desktop survey

Even before going out on site, old records and maps can be consulted to understand the history of a location.  Many old maps are now available online;  for example, the National Library of Scotland has scanned a national British set of 6 inch and 1 inch Ordnance Survey maps, along with other map series.  For example, the extract below shows the detail of the survey for Whitsbury hill fort (click on the map to see it in more detail).

Aerial Photography

Aerial photographs have revealed a palimpsest of archaeological remains throughout the Avon Valley, revealed as crop and soil marks.  Crop marks occur where buried features either suppress or promote crop growth, leading to variation in the colour and height of the crops.

The proliferation of online aerial photography has increased the resources available for research.  AVAS supplements this with the use of a model aeroplane, with attached camera.  A couple of members also have access to a private light aircraft.

AVAS members have identified a range of sites using aerial photography, including a possible Neolithic long barrow, numerous ring ditches which probably represent Bronxe Age barrows, as well as a series of enclosures and field systems.  The example below shows two ring ditches near Downton, recently revealed by aerial imagery.

Field walking

Field walking can be used to determine the distribution of surface finds and help identify new sites.  AVAS was involved in a major survey of the middle Avon Valley which was published in 1995.  This survey revealed a large number of new Prehistoric, Roman and Medieval sites, and helped to demonstrate the density of previous settlement in the Avon Valley.

AVAS members also get involved in more ad hoc surveys, as shown below where finds are being identified.

During this particular survey, a broken Palaeolithic stone hand axe was found:

Geophysics

Geophysics is a technique used to look for anomalies under the ground using electrical currents.  AVAS uses one particular type of geophysics, called resistivity, which measures the variation in an electric current as it passes between two probes in the ground.  Features buried underground such as ditches or walls will cause different readings.

Once a grid square has been surveyed, the results can be plotted, using colour to show the variation in the electrical resistance.  The plot below shows a composite plot of a survey done by AVAS members on a possible Neolithic long barrow (click on the plot to enlarge).

Excavation

Excavation is not undertaken lightly, as it is a destructive method of investigating archaeological remains.  AVAS has tended to use excavation to either rescue threatened remains, or as an evaluation tool where the topsoil is removed to get a clearer picture of what is under the ground.  This latter method is particularly effective in investigating anomalies highlighted by geophysics survey.  The photograph below shows AVAS members undertaking one such survey.
