A Derbyshire mother whose son drowned in a quarry pool in 2009 is continuing her campaign for more disused quarries to be filled in.
Ryan Walker, 15, died at the Far Hill Quarry near Ashover while swimming there.
Since then his family has fought to get the site made safe and warn other teenagers about the dangers of swimming in deep water.
An application to have the quarry filled in was turned down by the county council in September.
