[HOE] [HoE] Landslide Question

[Matt and Teresa Steflik <grifflik@stny.rr.com>]

Hey Folks -

Curious about how other Marshals would handle this:

Let's say you have a posse moving slowly up a steep incline covered in
loose rock.  Suddenly (for reasons beyond the posse's control), a
landslide starts from above them, consisting of said loose rock as well
as a number of medium to large sized boulders.  The posse desires to try
to dodge and/or outrun the landslide.  How would you calculate the
pace/acceleration of the tumbling rocks?  How would you take their mass
and acceleration into account in determining damage when they begin to
pummel the posse members?  Would you also include some variation of
"falling" damage as some unfortunate posse members gets swept up in the
landslide and carried along with it? Has this perhaps been covered in
Weird West already (or somewhere in Wasted West and I'm just not aware
of it)?

Any input would be appreciated - thanks in advance.
