 Snake Pass has also been closed for longer periods owing to subsidence in the local area following rain.In January 1932 the road was closed after 200 tonnes of debris fell on it during a heavy rainstorm, covering the surface in as much as in places.In January 2008 a landslip at Cowms Moor following heavy rain caused the road to be closed to all traffic between Ladybower and Glossop, although access was still available to local premises and businesses including the Snake Pass Inn.
