Dartmouth is well known for its variety of long-standing student traditions,[32] many of which are centered on the Green. At Homecoming each fall, a bonfire is constructed on the Green by the freshman class; students and community members gather to watch the freshmen run around it as it burns.[33] The wintertime celebration of Winter Carnival sees the construction of a snow sculpture on the Green.[34] In the springtime, Green Key Weekend is marked by concerts and performances on the Green, which until 1984 was also the site of fiercely competitive Green Key chariot races.[3][35]
