I have been trying to find the name of this movie for a long time.  I saw it as a kid back in the early 80s.  I think the movie might be from the 70s.  It is a western based movie with a group of men (robber type) who are crossing a mountain forest in search of gold.  They meet a skinny blonde girl who rarely speaks and joins them in the climb.  Soon one by one people start dying.  They are all shot by an arrow.  Since no one has any bow and arrow it creates a mystery and distrust in the group.  The bow and arrow is actually dropped off by the girl’s pet eagle when she signals it.  Finally only the boss and the girl is left and during a rape attempt she manages to stick a knife into him.  She finally empties all the gold and dumps them into a cavern.  It seems she was a protector of the treasure of the mountain.  If anyone has seen this movie please let me know the title as I badly want to see it again.  Thanks.
