I have posted about the archaeological study at La Boiselle a few times now, and have now found the website of the group carrying out the dig. It is well worth a visit and is updated regularly. It is very rare to be able to excavate a site of such importance as the 'Glory Hole' and the stories, images and finds are quite remarkable.
Interesting also for those with an interest in achaeology.
