The Duff Mound Tree on the Trail of 100 Giants is one of the largest on the trail despite its diminutive name on the trail guide. It is 24.5 feet in diameter level at the high side ground, has a DBH of 21.2' and is 231 feet tall. Its mound of piled debris upon which it stands has shrunk slightly from the windy fire passing thru, however it still sits a bit above the surrounding ground level. The trees center bole is broken off at about 165 feet height but is still approx 10 feet in diameter at that height.
