Siskind House
From Willipedia
Siskind House is one of the five Morley Drive houses--the others being Jenness, Hardy, Rice, and Miller. When Baxter was destroyed in 2004, several of the offices that were housed there moved to Siskind, including the Williams Outing Club and its equipment room, the Chaplain's Office, Community Service, and the Telephone Office.
How To Find Siskind
Siskind was unused for years before the destruction of Baxter, so many people still don't know where it is.
The easiest way to access Siskind and the other Morley houses is via the Science Quad. Go down the sidewalk between Physics and Jesup, towards the back entrance to Morley labs, and you will pretty quickly find yourself next to Rice (it'll be on your left), staring at an odd little sculpture garden in the middle of a cul-de-sac. Siskind is the furthest house on the right side of the cul-de-sac.
Morley Drive is also foot-accessible from Spring Street via a set of stairs up from the alleyway by the Purple Pub.
