to later railway works. The remains of a small rectangular stone structure (approx. by ) are located south of the road's edge. In 1988, Karskens noted that this resembled the station/stockade/hut remains found on the Great North Road, dating from the 1820s. Karskens also reported that an early hand-wrought iron tool, possibly the end of a pointed chisel or pick-axe was found on the surface of this mound, "strongly suggesting that it was connected with the early road works - perhaps a storage depot". There is also a series of other mounds of earth and stones approximately 2 metres in diameter closer to the edge of the road - these are possibly spoil heaps, either from early efforts to fill the rock-shelves or from later railway era works. The presence of the stone structure and other features gives this precinct of Cox's Road particular archaeological research potential. The proposed State Heritage Register listing of Cox's Road and Early Deviations includes six precincts of Cox's Road: Cox's Road and Early Deviations - Linden, Linden Precinct - HC Plan 2639 Cox's Road and Early Deviations - Woodford, Old Bathurst Road Precinct - HC Plan 2640 Cox's Road and Early Deviations - Woodford, Appian Way Precinct - HC Plan 2641 Cox's Road and Early Deviations - Mount York, Cox's Pass Precinct - HC Plan 2642 Cox's Road and Early Deviations - Hartley, Clarence Hilly Range / Mount Blaxland Precinct - HC Plan 2643 Cox's Road and Early Deviations - Sodwalls, Fish River Descent Precinct - HC Plan 2644 Condition As at 1 December 2014, the road was substantially intact. Numerous archaeological features from the 1814 road are evident including road fabric, such as sheet rock pavement, a low wall and small culvert, rock cuttings and rock cut drains. There is also physical evidence of a small rectangular stone structure to the south of the road formation. Heritage listing As at 10 November 2014, the surviving remnants of Cox's Road, built 1814 to 1815, have state significance as the earliest road across the Blue Mountains and the first structure built by Europeans west of the Blue Mountains. Building of this road followed from the prior exploration by Gregory Blaxland, William Lawson and William Wentworth, and the survey by George Evans. The successful construction of the road was symbolic of the conquest of the natural barrier created by the Blue Mountains, and represented Governor Macquarie's
