With buildings several storeys high and narrow pavements (boardwalks), icicles have little choice but to descend on to unsuspecting pedestrians below.
Ice blocks also slip from rooftops on to whatever is in close proximity. This is a serious winter problem that the city authorities are struggling to cope with.
