Up A Creek

It's a chilly autumn morning and a horseman, following the meanderings of a creek, pauses to look at the water falls which block his way. At the same moment, his horse senses "company" downstream. The "guest" is a mother grizzly who has wandered down to the water for a quick drink. All seems peaceful and serene . . . for now. But if you take a good look, you'll find a secret den that the mother bear intends to keep secret. "Bearing" this in mind, where do you think the horseman will find himself next?
