Andy Lewis, a record-breaking extreme athlete known for slacklining and for performing onstage with Madonna at the 2012 Super Bowl, dies in a BASE jumping accident in Utah, authorities say. Multiple outlets report the incident occurs Sunday in a remote canyon area near Moab, in Grand County, close to the Utah–Colorado border, in the Mineral Bottom area. The sheriff’s office in Grand County confirms one of the deaths is Lewis. Other reporting says a second man also dies in the same jump, though his identity is not widely provided. Several sources describe the sport as BASE jumping, which involves jumping from a fixed object such as a cliff and deploying a parachute to reach the ground, making it a high-risk activity. The reports characterize Lewis as a prominent figure in the niche disciplines of slacklining and tricklining as well as BASE jumping. Details about the cause of the accident and whether it involved a tandem jump are reported inconsistently across coverage, but all accounts agree that Lewis is among the two people killed in the Utah canyon incident.
