Sounder's illusive bay came up from a deep cleft.

Wallace plunged into a pinyon, climbed to the ground, skidded down a solid slide, to come upon an impassable the obstacle in the form of a solid wall of red granite.

At one point, if he had not been six feet five inches tall he would have been compelled to attempt retracing his trail--an impossible task.
