Tully Hill ASSI

The last Ice Age, 24,000 to 13,000 years ago, changed much of the landscape in Northern Ireland. Landforms and features from this era are important in understanding our glacial history and the events surrounding it. They were created by processes no longer active and so cannot be replaced once destroyed. Along with information from features and landforms in a greater area, Tully Hill near Kilrea helps to explain the nature of ice withdrawal within the Bann valley. Tully Hill is important because it comprises an outstanding example of an undisturbed deglacial landform - a major flat-topped delta with associated sand and gravel ridges to the south. These sediment deltas record temporary halts in glacial retreat, whilst the ridge alignment give clues to the direction of ice movement.
