With the discovery of an archive of photographs taken by a high school junior named Dan Garson, plenty.

Garson was just 17 when he hitched a ride from New Haven, Conn., to the legendary three-day music festival with the intention of snapping a few shots for his high school newspaper. A couple of photos ran in print, but the rest were stashed in a cardboard box in his parents' basement for decades.

Because Garson didn't stick with the news photographers covering the festival, "he took some fresh, unfamiliar images of Woodstock," says rock journalist Rona Elliot, who was the event's publicist in 1969. She's now the U.S. editor of Genesis Publications, which has published Garson's archive as part of a limited-edition book set, Woodstock Experience ($600, out Saturday).

Garson didn't live to see this weekend's 40th anniversary of Woodstock: He died of cancer in 1992 at age 40.
