Approaching Lock 77 along a new concrete channel. The towpath and ground on each side gradually drop away where the whole surrounding area has subsided due to mining.
Looking towards Lock 77. The original towpath, behind the railings, is about 5 feet lower at this point.
Lock 77, Anthony Lock, alongside Hulme Hall Lane, has been made deeper to compensate for the subsidence.
This means that the lock now has a fall (difference in level) of 15 feet 1½ inches, making it the fourth deepest lock on the UK canal system.
Leaving Lock 77. This picture gives a good view of the extra height added onto the lock chamber.
Approaching Lock 78, with Victoria Mill looming beyond.
