Yhared MUD uses a similiar system to this, but our weather system has
the ability to mess with tracks too... rain will wash tracks away, but
will also make the ground muddy for fresh tracks to be imprinted, snow
will cover up tracks but will also make new tracks very clear (until
the snow melts).  Hard surfaces such as ice and rock make leaving a
track a very slim possibility, but there is still a chance that a
faint track will be left.

Wounded creatures also leave blood trails unless they're bandaged up,
which makes the tracker's life a lot easier.  You may also want to
consider the fact that tracks aren't just about impressions in the
dirt.  A bloodhound can follow a very old scent trail for miles over
rock, and someone pushing through dense brush is going to leave broken
twigs and torn leaves (as well as scraps of clothing or fur/hair).
