Features and characters of the individual

This tree has a strange outline for a black walnut tree. This species has a tendency to have its first branches very high up, coming off its cylindrical trunk. This tree rather flared, rather than pyramid-shaped. The main branches on this tree are low down. Its characteristic bark is brown, dark, deeply cracked, as is to be expected. When its nut shells fall on the ground, their husks give off a sort of pleasant soapy smell. Another clue to finding it: it grows in tall grass, in a small clearing in the middle of the wooded area, next to a log cabin. The place really invites you to take a seat and enjoy the surroundings.
