The whale sculpture is located in a plaza outside the Lawrence Hall of Science. Other students in the area were taken inside after the girl was hit.

UC Berkeley does have an archery group, but its members practice on the other side of the campus.

Field trip chaperone Geoff Vassallo said the girl cried as she waited for an ambulance, but “was a pretty brave little girl.”
