We already know the slope angles on which avalanches can occur (23-45deg irrc), and that data is published and accessible. Avalanche conditions are much more complex, sometimes varying from slope to slope.

As for mitigation, it’s not uncommon for an avalanche to trigger after the 2nd+ rider to travel over the same area to trigger a slide, so to effectively mitigate a combination of techniques are required (see inbound any control on ski resorts using bombs, ski cuts, etc).

The best way to avoid an avalanche is to avoid avalanche terrain and understand the current conditions. It’s a risk/reward evaluation every backcountry rider needs to balance.
