Cherry making a photographic record of trench 3
Starting on Monday 1st August, the Caer Alyn Archaeolgical and Heritage Project is running its Summer Dig for 2011. This year we are investigating 2 cross ditches that cut off the promentry iron age hill fort that have shown up on a geophysical survey.

Lodge Field features II
Last look at the liner feature running through Trench 1 shows that originally it was over 20cm deep and running for approximately 200m long
Possible pit in Trench 2
A feature has been showing in the south eastern corner of Trench 2 since the first week. After cleaning back the area around it, the feature continues to stay damp when all the rest of the trench dries out. It is probably one of the large circular features on the geophys and could be part of the enterance.

Lodge Field features GPS survey results
As promised, I have surveyed the linear features using the GPS on my smart-phone. The GPS is said to be between 1m to 5m accuracy. The results have been overlaid on the aerial photo of Lodge Field below and show a fair representation of the layout of the linear features on the ground. The features are in fact straight, but I wanted to estimate the distance between them and see if they were parallel.
I only surveyed the features where they were clearly visible on the ground. In most cases, the features were between 10cm to 20cm deep and showing clearly in the vegetation.
The GPS results were saved as a .klm file and loaded onto Google Earth to take advantage of the measurement facility. The file has been laid onto the 2006 image which also shows evidence of ploughing as a comparison (upper left near the lodge between F1 and F2).
RESULTS
From East to West, the field is 194m wide. There are 9 linear features that are at least partially visible splitting the field into 10 strips. All features run on an approximate North/South bearing. Naming the features F1 to F9 with F1 being on the west of the field (left on the image) the distance between them were as follows:
F1-F2 27.4m
F2-F3 20.5m
F3-F4 19.3m
F4-F5 18.5m
F5-F6 13.8m
F6-F7 19.6m
F7-F8 19.2m
F8-F9 19.5m
I will carry out the survey again later in the week to compare the results.
Initial thoughts
On the ground, the features seem to be parallel, but the survey results show the F6,6,8 seem to be on a slightly different alignment as the field narrows. The strips are on average 19m wide, with this opening out slightly as the field widens in the west (F1,2).
