Ocean's Breath Plateau Why can't I cross this river?

The red man moved with a weakness within his gait, but he moved, and he wouldn't stop until every last bit of him gave out.

There was blood caked to his hip and a deep gash there, left untended (unless mud counts). A raw swath of pink and mealy skin showing through the umber-red of his fur there.

A scowl set upon Reyes' face, one eye squinting against the beam of sunlight stabbing at his vision. He sought cover but there wasn't much to be found upon the plateau.

His heart was set upon home. His mind a jumble, though.

With a weighted groan he settled down in a shady spot afforded by a tree that looked half as tired and worn as he felt, casting only a thin bit of shelter across the edge of the plateau's stones, but it would have to do. He eased himself awkwardly to sitting and tried to inspect his wounds.
