The Valley of Sheer Walls

The name of the land doesn't lie. This serene valley is surrounded by four sheer walls standing a proud 350 feet tall in a circular formation. Fortunately, the north has a wall that is only about a hundred feet tall with a tunnel throughout it which allows access, and allows the herd to exit if needed. There is a fresh water spring located near the south, a waterfall falling from the east, and a creek trickling from the west. The valley itself is about 450 feet in diameter. This is a good place to live as it rains often, but floods easily too. There are many different tunnel and cliffs that the horses could evacuate too if it does flood extremely enough. The predators that are outside stay outside, but the ones inside are trapped in there.
