The Avalanche Forecast

Route Choice Exercises

These route choice exercises were created by Simon Fraser University's Avalanche Research Program to test your ability to incorporate information from the avalanche forecast into your daily trip planning. You will take the information from the forecast and use it to decide which terrain you choose to ride, and which you choose to avoid. Please note that while these work on mobile devices, they're easier to use on desktop computers.

The avalanche forecast shows the danger rating for all three elevation bands; and the elevation and aspect of up to two avalanche problems. The terrain model shows three different route options. Assume the sloped areas on the model contain avalanche terrain. The blue areas are alpine, the yellow are treeline, and the green are below treeline.

Your goal is to rank the routes on the terrain model in order from least exposed to most exposed based on the avalanche forecast.

Have fun!
