The cairn on Hardendale Nab was excavated in 1986 in advance of destruction by quarrying, and this allowed the reconstruction of a complex sequence of development. Construction of the cairn appears to have begun in the Early Bronze Age, although it might have been earlier. Phase 1 comprised a simple cist burial, and small earthen mound, with a number of secondary burials made in and around the original monument. Unusual rectangular features might have been used for pyres. Phase 2 saw the erection of a round enclosure around the mound, which was later (Phase 3) filled with loose limestone rubble. Again burials, both cremations and inhumations, were cut into the rubble, and bone scattered over and amidst it, with an apparent focus on the southern part of the structure. The entire complex was buried by a further layer of rubble in Phase 4, into which several further burials, this time inhumations, were cut. The excavation produced an unusually large amount of environmental evidence, much of it associated with the use of the cairn as a roost by owls in Phases 2 and 3. [ABSTRACT FROM AUTHOR]
