Ha ha, very funny. Its really funny because here in my area where we hunt there are a lot of strip mines, now abandon and wooded over. Just about every deer my friend has shot since I've known him has ran into and died in one of these pits. Now these are normally about 30 - 50 yds wide and can be anywhere from 20 - 100 ft deep (almost vertical walls) depending on where the coal vein ran out. Makes for a difficult recovery sometimes.
