No doubt. All the big old growth stuff I have bucked into firewood here lately (mostly urban trees) were rotted out at the base. Large old maples and box elders were rotted in the centers, and full of mushy goo. Lots of black oaks (which are a type of red oak) in California that I dropped were full of water in the stump area, and gushed when cut into. A big leaf maple stump I cut up recently was about 6 ft DBH, and the landlord there was thinking it would make a great bear carving. I do not know why people are stuck on bear carvings. There are other subjects like this example:
