A large tree is downed here in the middle of the path, and you climb
over it.  Then, as you support your weight on it, you hear a not all
refreshing *SNAP*.  You suddenly are life-bruisingly lifted into the air as
the tree slams upward into your crotch, making you grimace in pain.  When
you land from being thrown about like a rag doll, you land straight on your
back foolishly.  Ouch, that hurt a lot.
