29 reactions | Here’s some really cool physical history. Notice the grooves in the cornice stones of lock 12? Those were made by decades of canal boats tethering to the land as the water level lowered and the boat headed down canal. Cool! Because, you don't know what you don't know! www.awesomeottawatours.com 815-343-4940 | Awesome Ottawa Tours | Facebook

⚠️ Avalanche Awareness — Cornice Collapse & Full-Depth Avalanche 🎥 This avalanche began with a cornice failure. A massive overhanging block of snow broke off from the ridge and crashed onto the slope below — triggering the entire snowpack to fail at full depth, resulting in a Size 3 avalanche. This kind of avalanche has enough force to destroy trees, bury a car, or wipe out a climbing team instantly. It’s a chilling reminder that the greatest hazards often start above you. 🏔 ⸻ 🧠 Understanding
