Members of Boulder's Congregation Har Hashem gathered in Eben G. Fine Park on Thursday afternoon for a Tashlich ceremony, part of the Jewish holiday of Rosh Hashanah.

"Tashlich" means "casting off" in Hebrew, and the ceremony involves symbolically casting off the sins of the previous year by tossing pieces of bread or other food into a body of flowing water.
