The presence of people disturbing the earth around Rodway is nothing new – it appears to have been going on for thousands of years! In February 1998, a burnt mound measuring 0.2 metres in height was excavated after being exposed during the course of pipe-laying work in the area. Such features are generally thought to be the remnants of prehistoric cooking sites, consisting of a heap of cinders and discarded stones that fractured after being heated on a hearth and dropped into a water-filled trough in order to boil meat. A sample of burnt deposits from the mound itself was carbon dated to 1000BC and the remains of a probable trough were located nearby, together with a grinding stone that would probably have been used to grind meal and sharpen tools. At least 12 burnt mounds are recorded around the moors (mostly on the boundaries of the island settlements and the watery peat deposits) while ploughing has levelled many other sites where burnt stones are concentrated.
