On New Year's Eve 1933, the Pickens Canyon flood and mud slide picked up speed and fury, engulfing much of Montrose. Those who survived described a deafening roar, trembling buildings and giant boulders skimming across the mud. The Montrose flood took at least 45 lives, and destroyed about 100 homes. It eventually prompted the building of an elaborate system of giant debris-trapping catch basins and other flood-control strategies that have greatly reduced the odds of another mudslide.
To honor the victims of that New Year's calamity and to mark its 75th anniversary, members of the historical society organized a remembrance ceremony on New Year's Day at a small monument built five years ago at Rosemont and Fairway Avenues, near where a doomed legion hall had stood.
