Canyon of Despair                                      -      N      -

The canyon is only about 100 feet to the surface here.  Water is running
down the eastern wall of the canyon and collecting in puddles.  This is one
of the only places that look good enough to exit the canyon.  The heat from
the desert above is having more effect on you here than in other parts of
the canyon since the sun is actually hitting most of you now.  
A large boulder crashes down from above and shatters directly behind you!
