A fan shaped pit and two similarly shaped large mounds of earth were visible as earthworks on digital images derived from lidar data to the south and north of the track to the east of the western entrance to the Honiton Tunnel.
It is probable that the visible earthworks were associated with the excavation of the Honiton Tunnel, built in the mid-19th century, or cuttings approaching it. Linear earthworks within the pit might be evidence of vehicle tracking. The spoilheaps were probably planted as plantations following the completion of the works, as depicted on the Ordnance Survey 25inch First Edition map.
