* The following is '''NOT''' a diagram of the steam tunnel system. Since this image has been seen by many people and seems to have reached legend status, I am not deleting it in order for this explanation to make sense and hopefully reach the people who have been wrongfully informed. This map is of affiliated clusters of houses directly after fraternities were abolished, when the fraternity buildings were still commonly known by their Greek letter names. As far as I know, these houses were affiliated by where their residents ate, among other shared activities. It should be obvious to anyone viewing this map anyway that the network drawn in color would be a woefully inefficient system of steam distribution and does not even connect in many parts to the main distribution plant in the southeast part of campus.
