The Dyke leaves the left bank of the March Burn to run westwards across the Spout and Docken Burns. It is barely visible for much of this stretch, and fades out entirely upon entering the marsh that has formed at an angle in the Park Burn (666124). It appears again 200 yds. to the SW., where it is joined by a bank of very similar appearance which starts a quarter of a mile to the E. on the left bank of the Docken Burn. The Dyke now passes under a field-wall and soon crosses the 1000-foot contour as it runs WSW. towards the Garepool Burn, a distance of 800 yds. For much of this stretch the Dyke is accompanied along its higher side by a modern field-drain, but it can nevertheless be distinguished as an earthen bank, containing a few boulders, which measures from 9 to 12 ft. in width and stands 1 ft. or a little more in height. The Dyke has here been wasted and interrupted by cultivation, and it finally dies away about 100 .yds. E. of the Garepool Burn. Westwards of the burn, for about 700 yds., the Dyke runs WSW. and is largely overlain by a modern field-wall. But at a point 140 yds. E. of the Gatelochside Burn, where a nameless sike rises, the Dyke turns W. and the wall SW., the former now reappearing on a somewhat sinuous course at a level of about 1150 ft. above sea-level. It crosses the Gatelochside Burn and runs off across enclosed but coarse pasture to the W. for a quarter of a mile, and then to the SW. for about half that distance to the Bye Burn. Here it is seriously mutilated by drainage-ditches and field-walls for a distance of about a quarter of a mile, but finally emerges to run uninterrupted for nearly 700 yds. across the foot of Burnt Hill to reach the Polquhirter Burn at a point a quarter of a mile above the junction of that burn and the Redree Burn. Westwards of the Polquhirter Burn the Dyke continues in the same line for a quarter of a mile, until it is lost in marshy ground a few yards NE. of B.M. 1044-1 beside the Redree Burn (6-inch sheet (Ayrshire) XLII SW.). The ground W. of the burn is called Black Moss, and the earthwork appears only on the north-western margin of the boggy ground at a point distant about 150 yds. W. of B.M. 1044-1. From here it increases steadily in size as it rises up the slopes of Dalhanna Hill on the course' shown on the O.S. map as a thin black line, passing a few feet NE. of the summit of the hill. Here, at 1220 ft. above sea-level, the Dyke attains its highest altitude and appears as a ditchless bank standing up to 2 ft. in height and spread to a thickness of about 12 ft. Descending the north-western flank of the hill, and running under a field-wall, it is soon lost, at a height of about 900 ft. O.D., in the field that slopes down to the Afton Water more than 200 ft. below

From NS 6171 1143 to NS 6199 1126: The Dyke descends the NW flank of the hill and is lost, after running under a field wall at about 900ft OD (Graham and Feachem 1956).

From NS 6202 1123 to NS 6278 1104: The Dyke is up to 2ft high and spreads to about 12ft where it attains its highest altitude (about 1220ft) (Graham and Feachem 1956). At NS 6287 1107: It reappears on NW margin of boggy ground about 150yds W of benchmark 1044-1 (Graham and Feachem 1956). From NS 6306 1118 to NS 6352 1136: The Dyke continues in same line for a quarter of a mile until lost in marshy ground a few yards NE of benchmark 1044-1 (Graham and Feachem 1956). At 6352 1136: RAF vertical aerial photograph (106G/ SCOT/ UK90, frame no 4175, 1946.) From NS 6352 1136 to NS 6409 1161: The Dyke runs uninterrupted for nearly 700yds across the foot of Burnt Hill, to a point a quarter of a mile above junction of Polquhirter and Redree Burns (Graham and Feachem 1956). From 6409 1161 to NS 9448 1175: This section is seriously mutilated by drainage ditches and field walls for about a quarter of a mile (Graham and Feachem 1956). At NS 6415 1165: RAF vertical aerial photograph (106G/ SCOT/ UK90, frame no 4176, 1946.) From NS 9448 1175 to NS 9466 1181: The Dyke runs SW for about three-eighths of a mile (Graham and Feachem 1956). At NS 9466 1181: RAF vertical aerial photograph (106G/ SCOT/ UK90, frame no 4177, 1946.) From NS 9466 1181 to NS 9497 1185: It crosses a coarse pasture to W for a quarter of a mile (Graham and Feachem 1956). Information from OS 1985. A Graham and R W Feachem 1956
