Mosher-Jordan, or "MoJo", is one of the Hill Dorms. It is on Observatory Street. MoJo houses only a few hundred students, and is small enough that meals are not served on weekends.
The third floor houses the "UROP in Residence" (Undergraduate Research Opportunities Program) members, and the Fifth Floor houses members of the Women in Science and Engineering Program (WISE). MoJo is being renovated 2006-8 (or 2007?), so WISE has moved to East Quad, joining the Residential College.
Since the renovation the Hill Dining center is one of the largest and most popular dinning halls on campus, open every day of the week. MRC (formerly "UROP in Residence") and WISE both room in MoJo. This dorm is also one of the most sought after on campus.
In the news
When students begin moving into the completely renewed Mosher-Jordan Hall this week, they will live in air-conditioned rooms, have access to wireless Internet and the ability to choose from seven food stations in the adjoining new Hill Dining Center. Mosher-Jordan Hall, which opened in 1930, has been completely upgraded, yet the gracious traditional architectural style and details have been preserved.
