Avalanches can race downhill faster than a sprinting athlete
Dry slab avalanches can accelerate to 80 km/h or more within seconds, outrunning people on foot and burying them under tons of compacted snow that sets like concrete.
Weak layers buried under a cohesive slab fail when weight, weather, or a skier’s cut triggers collapse. Terrain traps — gullies and trees — raise the odds of deep burial.
Mountains keep score in snowpack. Beacon practice, slope choice, and waiting out unstable days matter because you cannot outrun a moving hillside once it breaks.
