List of tunnels

This page is a list of tunnels.

Old Mudd/Uris/Havemeyer tunnel system(since replaced)

One steam tunnel system connected Mudd Hall, Uris Hall, Dodge Fitness Center, and Havemeyer Hall, and was generally considered the easiest to access. These tunnels contained an old rail track that was used to transport coal for heating. They also contained the "Signature Room," where one can find many quotes and names left by previous tunnelers. This tunnel system also used to connect to the first floor of Pupin Hall, but that way was blocked in the 1990s.

Until the Summer of 2003, the first floor of Pupin was virtually untouched from the last days of the Manhattan Project. Notes and daily logs scattered dusty tables. Half-completed experiments sat in stasis, only visible to the few explorers who got in. Since 2003, the first floor has been cleaned out, and is now mostly empty. However, one of the first cyclotrons remains, though it is difficult to access.

This tunnel system was made obsolete by the chiller plant expansion.

Mudd/Uris/Schermerhorn System

The grand majority of this tunnel system is public access and consists of the area in and around the Mudd parking garage. The easiest way to get in is to simply take the Mudd elevator to the basement level and follow the hallway out through the swinging doors into a parking garage.

To the right of this big room should be a door leading into an open-air breezeway with stairs up to the plaza in front of Mudd. This door is locked from the outside, so bring multiple people or prop it. Once you get into the breezeway, there should be locked doors on the left and right that enter the power plant system.

To the left of this big room past the exit driveway, there should be a set of automatic doors which lead to a set of maintenance and storage rooms. One should be aware that there are many more cameras through this doorway, because as soon as you enter it, there is yet another card-access entrance to the chiller and power plant on the right. The ramp up to the right leads to Schermerhorn extension if you follow the corridor all the way through. The corridor to the left has some cool remnants of CU history for avid readers of the wiki or likewise.

New Mudd/Uris/Havemeyer system

There are a few known ways to get into the new chiller system. From the Havemeyer side, simply enter the Math/Kent/Havemeyer system and there should be a door hiding in the corner as you approach Havemeyer from Math.

Other tunnel systems

Another tunnel system connects Havemeyer Hall, Math Hall, Lewisohn Hall, and the Miller Theater.

A tunnel between Butler Library and Low Library is rumored to exist, but no evidence of such a tunnel has ever been found. Any entrance to this tunnel from Butler Library is well hidden or heavily locked, and the Low Library entrance would be next-to-impossible to find given that Campus Security is based on the first floor.

There is no tunnel to the Barnard campus (except that you can just walk through the subway station), and almost definitely none to East Campus.

Inaccessible tunnels

Buell to Low

This passageway does exist, but it's a tiny crawlspace filled with steam pipes that are hot to the touch. It probably also contains asbestos. You can see it from the Kent-Buell passage, but the way to it is blocked. Don't even think about climbing over the pipes, because if you try, you'll burn yourself badly. These pipes, like all the pipes in the Buell crawlspace, don't have any sort of insulation on them - which is why it's always hot as Hades in there.

You can climb over the pipes, but the passage ends with a cinder-block wall after you crawl about 100 feet. Be wary that the way back out will require crawling in reverse until it opens up enough to turn around.

Unconfirmed/speculated tunnels

• Mental Institution Foundation tunnel. Apparently, these tunnels can be found beneath the lower level of the Old Powerhouse.
• Butler to Low tunnel
