You lose your footing and slip down the slope.  This is the direction you
were trying to go, just not in this particular fashion.  You scramble and
manage to regain your balance.  There is no way of getting back to where you
came from you can only follow the southeastern slope downward.  That doesn't
bother you terribly, since you have very little desire to go back up that
mountain.
