The Dean Tree is 23 feet in diameter level at the high side ground, 21.5 feet diameter at chest height, and 236 feet tall. It was first reported by Grace Alles, who probably learned of it around the year 1900. Flint said it was named because the name Dean was carved into it by an unknown early pioneer; however, information on this tree is limited and confusing. The name might actually refer to another nearby tree, or there may be two trees that had the name Dean carved into them. Either way, I think the tree's size is underrated; if my most recent measurements are correct, it deserves to be higher up on the list.
