Dartmouth College is again honoring one of its most famous graduates with the theme of this year's Winter Carnival: Seuss on the Loose.

Colorful posters advertising this weekend's event show the Grinch suspended by ropes over a frozen pond. It's the fourth time carnival planners have honored Dr. Seuss's literary legacy by making his characters part of the carnival theme.

Seuss, whose real name was Theodor Geisel, graduated from Dartmouth in 1925. Donald Pease, a Dartmouth professor and Dr. Seuss scholar, said Geisel loved the carnival and sometimes invited his family to join him for the annual celebration of winter sports.

The carnival began in 1911 and has expanded to span three days and multiple locations across campus. In addition to ski races, the carnival includes an ice-sculpting contest and human dogsled races on the college green.

This year's festival, which ends Sunday, includes several Seuss-themed events, including a late-night breakfast featuring green eggs and ham, and screenings of movies based on Seuss's books.
