Jack would like to extend a big thank you to everyone who came along to help out with processing the soil samples at Castlehill Heritage Centre last month. We discovered that many of the samples are relatively rich in charcoal, and there are a small number of grains of barley as well. The charcoal and cereal will provide the best chance of dating the site, and might also help us to understand what the site was used for, and if this changed over time. Our volunteers have begun to analyse the soil samples for Ph (acidity/alkalinity) and phosphate levels. These indicators of human activity can provide clues about land use in the past, for example whether soil contains traces of animal manure, which might have been added intentionally as fertiliser, or may be an indicator of the presence of animals kept for meat or dairying activities.
We will keep you posted as the post-excavation analysis progresses!
