The Krentzman Quadrangle, also known as the "main quadrangle", is the open area bounded by Richards Hall, Ell Building, Dodge Hall and Huntington Avenue (and the wall). It is dominated by a central grass mound, known sometimes as Mount Ryder after former president Kenneth G. Ryder under whose tenure the quad was greenified. It centerpieces the traditional main facade of the university.
This quad has been used for a number of programs such as "Camp Out on the Quad" and the Greek Week see-saw marathon. The other significant fixture here is the black clock.
