Thats what maps are for, on the GPS or on paper. If you don't know
where you are on the map, due to weather conditions, you can't
avoid hazards. (ridges that may be corniced, slope angles that
are conducive to avalanche, runs shown on the topography, aspects with weak snow layers etc.)

And there have been some software programs that will print a map
with some of the variables that predict avalanche danger.
