The gully runs through the middle of Treeclan territory, eventually reaching out beyond the border. The walls, roughly six feet high, are covered in a variety of large ferns and moss. The gully often holds debris such as fallen branches and logs, providing shelter and hiding places for cats and prey alike.

The back of Treeclan territory is framed by a low mountain range. Built into the rock walls is an old temple, built by twolegs from eons past. Inside, the temple is a large maze with many dead-ends and only other other exit leading into loner territory. It is very easy to get turned around once inside the cramped, low tunnels.

Slumbering Lake is a small, yet deep lake of water. The first few feet are fairly shallow, but the floor drops out quickly and the water becomes deep enough that the bottom cannot be seen. In the middle of the hot season it often provides a welcome relief for cats seeking to escape the heat. Along the banks of the lake a variety of herbs and colourful flowers grow.
