Rogers Pass avalanche was March 4, 1910. According to Parks Canada, more than 250 men were killed on Rogers between 1885 and 1911. It's not stated whether all of these fatalities were involved with the railroad, but I imagine during that time period there wasn't much else going on at Rogers but the railroad. Yes, it's a story worth telling, but the one that's clearly been worth a novel or two, as you already know (and have had a personal hand in), was Wellington due to its higher single-incident death toll, and the sheer drama of two trains literally being swept off the side of the mountain.
