ANAM includes a category for skiing. Near the end of the 2013 ANAM, there is a footnote about it:
[size=10pt]This category was set up originally for ski mountaineering. Some extreme-ski incidents qualify. Backcountry ski touring or snowshoeing incidents—even if avalanched—are not in the data.[/size]
The 2012 ANAM has a report about a steep skiing fall (non-fatal) in the Tetons. Pretty interesting. I haven't looked for other reports.
It would be interesting to talk to somebody associated with ANAM about the reports they publish. I suspect that free-solo climbing and steep skiing accidents don't get written up very often.
My guess would be that since the danger is so obvious, people are reluctant to analyze it afterward. It's like, if you succeed you're a hero. If you fall, you should have known better.
I've heard of several instances where the surviving partners of those who fell didn't want to talk about it.
