| Description: | Road under Wollacombe Down. Looking NE. Artificial section of 'head' or unassorted detritus formed under conditions of severe cold. Although no true glaciers formed in Devon the severe frosts of the Glacial period affected the county. The temperature fell to probably many degrees of frost and as a result the ground-water was frozen to a great depth and there were no springs. Seasonal thaws affected only the upper few feet of rock but the sudden thawing of many years of snowfall coupled with the weakened rock exposure led to great flows of earth and broken rock fragments, 'head', to fill lower hollows. |
