This was where Peter Sam had an accident with some slate trucks, it was caused when some slate trucks broke the winch pulling them up the incline. Some slate trucks later broke the winch again, which caused then to crash through some buffers, causing an avalanche and trapping Skarloey under it. Duncan was once being very impatient to finish his work at the quarry, which caused him to be dragged up the incline with his slate trucks. The winch then broke and he, with his slate trucks, fell into the muddy ravine.
