Tumulus at Aldridge
There is a mound at the cricket ground at Aldridge. Mike Shaw asked
WAG to go and record it.
2/8/2001. WAG has at last got started. On a rainy day in August, 4 intrepid
Archaeologists, Annie, Jan, Graham and Martin converged on a mound in
Aldridge. The aim was to:
- do a Geophysical (resistivity) survey
- do an earthworks survey
It was difficult to lay out 20 metre square grids as the mound was about 2 metres high
and there was too much distortion when using the tapes. More success was obtained by
going to 10 metre grids and using the theodolite to set the angles to the corners.
Would the survey, planned for the next day go as smoothly?
3/8/2001 The next day the same 4 intrepid archaeologists braved the weather which
threatened all day but did not actually put a stop to things. In fact we were hoping for
rain because the mound was so dry that it was difficult to get resistivity readings that
were on scale. Eventually, the loggers' current was changed from 1 milliamp to 0.1 milliamps
and that did the trick. Surveying 10 metre squares was done in no time at all.
Aldridge must have a better class of kid than most places. We had left some squares marked
out with tent pegs the previous evening and we had noticed that the mound had been used by
kids on their BMX bikes. When we arrived that morning, we found 2 tent pegs carefully laid side
by side underneath a tree so we would see them. They must have been in the way of the bikers,
but instead of throwing them into the undergrowth they left them where we would find them.
Well done, lads!!
16/8/2001 A fortnight later we were back! The aim of the exercise was to do an earthwork
survey. The problem was - how to measure a lump? Eventually we plonked the theodolite on the
top and took heights along the radii ( at 0, 20, 30 degrees etc).
From that we hoped to be able to
draw a plan, contours and cross sections. We got halfway round by the time to go home.
17/8/2001 Today, as we knew what we were doing, we completed the radials and added some half
radials in between (at 10, 30, 50 degrees etc). In addition, we surveyed some of the features on the
mound ( there are at least two scooped out areas which might be erosion and 4 paths). We even tried
some divining.
There is something there - but what? The weather had
been kind to us on both days and we all looked as if we had caught the sun. Who needs to go
abroad? Come to wild and windswept Aldridge!
19/8/2001 We cannot keep away. Today we (Jan and Martin) took Emma to look at the sight.
She counted the number of species in the hedgerow to try to get an idea of its age. We also
explored local pathways, a ditch and wondered about the number of Willows around. Emma hopes
to study the grasses next time (24/8).
24/8/2001 An invasion today! Jan, Emma, Sandra, Graham and Martin descended on Aldridge.
We completed some extra geophysics grids (now 17 in all), did some divining and picked blackberries.
Who said archaeology wasn't fun? Seriously, most of the physical characterisation of the mound has
been done, we need to determine the level now from a nearby benchmark and then put it all together
in a report. Watch this space!
27/9/2001 Jan, Sandra, Sue and Martin this time. We had some telephoned instructions on how
to set up the magnetometer from Tony Habberley so we thought we would try it today. All our grid pegs
had disappeared so we set some new 10m grids up north/south on a faithful Oak tree and we were away.
9 grids later, we were all sunburned and ready for home. The results were inconclusive, the magnetometer
setup is quite critical so we will probably have more success next time.
July 2002. A quick visit to Aldridge to check the drawing.
The groundsman says the mound is going to be flattened to make way for a new
Astroturf ground, the Borough Archaeologist says not, but it would be
interesting for someone to be there if it happens.
Remaining jobs are to transfer the benchmark, complete the desktop survey
and to draw the earthwork survey.
March 2003 Finally written and handed to Mike Shaw for comments.
Copies will be available and, hopefully, a short report for CBA West Midlands.
