The rotational aspect of a slump is well-displayed in this slump block (to the upper-left of the sign) in the North Unit of Theodore Roosevelt National Park. Compare the tilted orientation of the bedding in the slump block relative to the horizontal bedding in the background.

The age of this particular slump is unknown, but it may be at least several centuries old.
