One of the most interesting and awe-inspiring locations in which the Royal Canadian Pacific pass through most certainly is the town of Frank. Nestled in the southwest corner of Alberta, Frank is home to one of the largest and deadliest landslides in Canadian history, the Frank Slide. Occurring on the morning of April 29th, 1903, the Frank Slide was a rockslide that buried part of the mining town of Frank, in the Crowsnest Pass, at approximately 4:10AM. Over 90 million tons of limestone rock slid down Turtle Mountain within 100 seconds, obliterating the eastern edge of Frank, the Canadian Pacific Railway line and the coal mine. Between 70 and 90 of the town's residents were killed, most of whom remain buried. Over 100 years later, the site remains mostly unchanged, and one can only marvel at how the rocks dwarf the 4107 and its train.
