May have learned more about terrestrial snow avalanches than those on Mars, and it was interesting.

I'm not familiar with purely linear avalanches, the ones I've seen have fanned as far as the terrrain would allow. Neither have I seen the upslope propagating avalanches, but thinking about it there's no reason it couldn't happen.

It's hard to get a sense of the slope from the pictures, visualize exactly what's happening. While these may be moisture mediated, they sure don't look as if real, live water were involved.

But, what I know is completely embodied in those papers.

Thanks again.
