Keeper's Pass North is the 5th Transition Zone Region that connects to Keeper's Pass South via a cave system, which in turn connects to Pleasant Valley, and Blackrock to the north. It consists of winding ravine passages and a river that cuts through the region with a rickety bridge going over it. It has no interior shelter, but Forester's Hermitage does provide a bed and fireplace. At the bottom by the river there is a cave with a Distress Pistol case and a stick bed; to get there, a rope must be traversed.
Currently, neither part of Keeper's Pass is featured on the World Map, but regional maps are available for these regions.
The section from the transitional cave system to Forester's Hermitage is the section that Mackenzie runs in the beginning of Episode 4.
