A day or two ago an email from the Alpine Club indicated that numerous climbing incidents, of varying severity, have resulted from hiking route apps including technical routes. While this was specific to climbing there is no reason to believe that skiing and snow sport activities couldn't be subject to the same misleading information from various sources. There has also been no shortage of vehicle incidents resulting from Google maps and similar sources.

When it comes to on-the-snow routes for skiing, riding, etc, beware of accuracy on parameters such as slope angles. The last AIARE Level 2 fatal accident a few years ago occurred on a slope which the group had analyzed online or on a computer beforehand. Their slope angle estimate was off by a few degrees, which can make a difference. (We can't say in that case if that was a specific factor among others, but it's possible. And it could play a role in other locations and situations as well.) Other factors such as vegetation, alleged summer roads and trails, etc, may or may not be entirely accurate.
