The sand from the desert is starting to burn your feet.  The only escape
from the sun looks like that large canyon to the east.  This seems to be the
only way that you have seen to get down to the floor.  Going east will take
many miles.  
A vulture is scavenging for dead carcasses here.
A large, red scorpion is here flashing his stinger.
