Around 1884, the Zimmerman family, prominent members of the Aurora Colony, planted this black walnut. Early Aurora settlers were talented and industrious, and their products gained a wide reputation for excellence during the early days of Willamette Valley settlements. As a carpenter, Christian Zimmerman helped build the village and likely planted this tree and others like it for the valuable hardwood. The tree has a circumference of 18 feet, a height of 70 feet, a crown spread of 60 feet, and an approximate age of 130 years.
