A huge gorge marks the RiverClan border with WindClan. There is a brief transition between reedy marshes and open, grassy mores before this gorge. The land becomes drier and rather rocky. This gorge is dangerous, and at the bottom is a swiftly flowing branch of the river. Even the strongest RiverClan swimmer would be easily swept away. The gorge splits the land until fairly close to Fourtrees, where it narrows out and becomes shallower, and the source of this water - a spring bubbling out between two rocks and then falling down the length of the gorge - is visible. The gorge is impassable unless a cat wishes to completely go around it by way of Fourtrees. Invaders from the WindClan side are fairly thoroughly blocked out, and RiverClan cats can easily guard the several foxlengths between the gorge's end and Fourtrees.
