Avalanche fatalities while solo and going uphill
Mark Staples

One of the most basic things we all learn in introductory avalanche classes is to only expose one person at a time. The idea is to limit the number of possible victims to one. Unfortunately, there have been four events this winter involving multiple avalanche fatalities (2 in CO, 3 in CO, 3 in AK, and 4 in UT).
If we say that only one person should have died in each of those avalanches instead of multiple people, then there should have been four fatalities and eight people still alive.
Regarding solo travel and being …

Historical Context about Avalanche Fatalities
Mark Staples

If avalanche fatalities were to follow the monthly averages for the rest of the season, here is what the 30-year averages …
