class of 1859. In 2016, a college-wide contest was held for a new official Williams song. The winner was "Echo of Williams", music by Kevin Weist, class of 1981, and lyrics by Bruce Leddy, class of 1983. Mountain Day On one of the first three Fridays in October, the president of the college cancels classes and declares it Mountain Day. The bells ring, announcing the event, members of the Outing Club unfurl a banner from the roof of Chapin Hall and students hike up Stony Ledge. At Stony Ledge, they celebrate with donuts, cider and a cappella performances. The first known mention of Mountain Day was made in 1827 by Williams president Edward Dorr Griffin in his notebook on college business. He wrote, under 'Holidays': "About the 24th of June a day to go to the mountain. If not then about the 14th of July. Prayers at night." In 2009, with the threat of bad weather for each of the first three Fridays of the month, Interim-president Wagner declared "Siberian Mountain Day". Festivities were relocated from Stony Ledge to the much more accessible Stone Hill.

The "Little Three", a subset of NESCAC, comprises the three schools Although Williams College typically sports purple and gold as their school colors, purple is in fact the only school color. The gold was added in order to differentiate its colors from that of rival school Amherst's purple and white uniforms. On May 3, 2009, Williams and Amherst alumni played a game of vintage baseball at Wahconah Park according to 1859-rules to commemorate the 150th-anniversary of the first college baseball game, which was played on July 2, 1859, between the two schools. Until 1994, Williams was not permitted, by NESCAC rules, to compete in team NCAA competition. The Williams women's swimming and diving team won the school's first national title in 1981, and claimed the title in
