Today, Sunday 5th Dec, is World Soil Day. Soil is of course very important to archaeologists, and variations and features within soil can tell us a lot about the past. For instance, it is important to sieve all excavated soil, to avoid missing any small finds, as can be seen here.
(This image was taken at excavations in Harlaa, Ethiopia, on land belonging to landowner Hindi, who is shown sieving in the photo. Here, our research fellow Dr Nadia Khalaf, who took this photograph, was excavating a 12-14th century settlement.)
