The chalky structure of the hill means that much of it is hollow. Over on the highest point of the common many houses still have wells in the kitchen from which residents obtained all their water. It is only within the last 50 years that these homes were connected to the water mains. One, named appropriately "Well Cottage", is only just having mains water connected as part of refurbishment following its recent sale.

Having a hollow hill has also brought pleasure to recent generations. In addition to the earth having a nasty habit of collapsing inwards, the area was extensively mined for the clay. This was generally restricted to the wooded areas and has created what are referred to as the dells. In the wet season these fill with water, but after a dry spell the water drains away and the dells form a natural playground for mountain bikers to practise their stunts.
