The HBLSS has a long history of campaigning, members never afraid to take up the cudgels on issues as varied as tree felling, overhead cables, the closure of public footpaths and wind power.
Most prominent – and enduring – of all the battles, however, centred on the threat to Hardcastle Crags which began in 1934 when Halifax Corporation set its sights on turning the much-loved beauty spot into a reservoir.
The Hardcastle Crags Preservation Committee, backed by the HBLSS, was formed and successfully fought off the moves. It was reformed in 1948 when Halifax revived the proposal – and yet again in 1967, when the same plan was mooted and became a major cause for contention throughout the upper Calder Valley. The scheme was finally dropped in 1969.
In 2000 the Local History Society supported Heptonstall residents in their bid for funding for St Thomas `a Becket Church and in 2001 gave its backing to the formation of a Mytholmroyd Conservation Area. Members have also opposed plans to move local archives away from the area.
