fabric appearing to date from a later era than 1814. The modern unsealed farm track which coincides with the Old Bathurst Road runs some distance north of the line surveyed by McBrien in 1823. Cox's original road in this area likely required little cutting or forming over the easy grades, and therefore did not leave extensive physical evidence. There are remnants of pavement, quantities of cut stone, stone retaining walls of different sophistication and style, a constructed road zig-zag and stone box-culverts, all of which appear to relate to much later 1820s improvements. The reserved Crown Road diverges from the unsealed farm track and begins to climb to the southwest through more thickly timbered country. Here parts are cut through pink granite and various partly worked stone is lying around with short sections of retaining wall and some early road pavement evident, generally with a width of about . At approximately from the base of the hill, the road is formed into a substantial zig-zag which extends for . The zig-zag is supported by carefully constructed retaining walls which commence with a single course of roughly broken stone as edging and then rise steadily to about in height, with some stones squared, many not, but with a relatively smooth face. The bonding is random with the largest stones at the bottom and an even coping course at the top. The road here also features a packed stone pavement. Various piles of broken or worked stone left over from building operations scattered beside the road formation. There are also some sections of earth-faced cuttings and the road formation increases in width up to wide. At approximately from the end of the wall, a primitive stone box culvert is present, wide and deep, set on walls of two courses of squared stone, with a roughly cut lintel and an earthen floor. On the opposite side is a depression over the inlet area, and section of stone edged side drain is visible. The drain may continue further back down to the zig-zag , but it would need archaeological work to clear and excavate the area to determine this. Although McBrien's 1823 survey follows the line of this zig-zag, Grace Karskens has argued that comparative archaeological evidence suggests that the stone walls, formation width and pavement were added later as part of improvements to the original Cox's Road. Karskens comments that: In the vicinity
