Clifty Falls State Park in eastern Indiana, at the border to Ohio, features a large canyon with several waterfalls, about 20 meters tall.
This allows for views that are not very common elsewhere in Indiana. Usually, when your view is not blocked by trees, it is an endless plane and an endless sky, cut in half by a perfectly straight horizon. At Clifty Falls, you can look across, giving you back a sense of size.
Or, if you dare, you can look down.
It is somewhat ironic that the only reason lonely trees have a chance to grow this tall is the protection of the canyon they are trying to outgrow.
