Walnut bark is normally shaggy and rough, but if you can pull it away with your fingers, the tree is dying or dead. If the bark is peeled all the way around the trunk, it's definitely dead. If the tree's cambium layer is exposed, it cannot pull water and nutrients from its root system to the canopy, and the tree dies.
Also asked, how do you know when a black walnut tree is dying?
You may notice yellowing or spotted leaves, or in the case of cankers, black, sunken spots on the bark. If the canker completely girdles the trunk, the tree is likely dead or will be soon because nutrients can't reach the roots.
