The only deciduous black oak of the western U.S. occurs in the Sierra Nevada and Coast ranges of California and North to Southwestern Oregon. A large graceful tree, sometimes 100 feet high and 4 feet in diameter, whose trunk is usually short and much branched. The wood is hard and strong but sometimes rather brash. Properly seasoned it is comparable to eastern red oaks. The lumber is used for pallets, cabinets, furniture, panelling and industrial timbers. It is also much sought after for firewood and chips.
