On my way to the library, I found this tree with an abnormal shape that deviates it from its same kinds.  Unlike others, the trunk of this tree is so stumpy that you can barely see it, and the three vigorous branches form the main body of the tree. One of the branches crawls forward close to the ground, directing toward South College. The other two both grow upward, but each points toward different directions. I think the shape of this tree resembles Susquehanna Rivers. The branch close to the ground is the main body of the river, and the two branches point toward the sky are respectively north branch and west branch of the river.
