Oak Log Trees are exceptionally huge Oak Trees. They often resemble many-fingered hands with the palm upwards.
The Oak Log Trees have a new trunk, similar to the Redwood and Fir logs. The trunk of the tree being four different logs together making one big one.
Oak Log Trees can be found in Biomes that naturally spawn trees. They are randomly generated. These trees are affected by the TreeCapitator mod, so be careful when chopping them down as they may cause significant lag from the sheer quantity of logs.
