On April 29, 1903, 110 million tonnes of limestone crashed from the summit of Turtle Mountain and buried part of the sleeping town of Frank. The rock mass that fell was 150 metres deep, 425 metres high and one kilometre wide. The bustling town of Frank was home to approximately 600 people in 1903. Most of the roughly 110 individuals who lived in the path of the slide were killed. The primary cause of the Frank Slide was the mountain’s unstable geological structure. Underground coal mining, water action in summit cracks and unusual weather conditions also contributed to the disaster.
