The recent drought in Ireland has exposed ancient henge structures, revealing post holes that have left distinct soil patterns visible from aerial views. The decay of these post bases has resulted in soil that is more resistant to desiccation compared to the surrounding areas. This phenomenon raises questions about the cultivation history of the region and the potential for measuring soil accumulation rates, highlighting the long-term impact of human activity on the landscape.
Archaeologists, soil scientists, historians, and anyone interested in the effects of climate on ancient landscapes.
