The slackline, similar to a truck-towing strap, was stretched chest-high between two trees. In what has become a popular sport, students balance and do gymnastics-style tricks on the line, the Salt Lake Tribune reported.
Anderson, 24, a music major and marching band member at the school, rode his bicycle into the line and sustained upper body trauma, including head and neck injuries, when he struck the line Monday afternoon, school spokesman Tim Vitale said.
Anderson was rushed to a hospital after paramedics could not revive him at the scene. He was reported unresponsive when transported, and declared dead an hour later, the newspaper said.
