The road hugs the river, culminating in a bridge that once spanned the flow, leading to the mouth of the valley. Scorched, scarred earthworks are all that now remain of a long abandoned fortification. The great rents in the defenses must have been torn by a devastating force, exposing a massive shard of black rock resting at its heart.
