Authorities say a California man has died while wingsuit-flying among remote cliffs on the Arizona-Utah border.

The Coconino County Sheriff's Office said Wednesday it was devising a plan to recover the body of 29-year-old Mathew Kenney of Santa Cruz.

Sheriff's Lt. Bret Axlund says Kenney's body is trapped in a crevice about 600 feet below the spot where he jumped Tuesday in Paria Canyon-Vermilion Cliffs Wilderness.

Axlund says Kenney was among a group of experienced wingsuit fliers. He says Kenney hit a wall but investigators aren't sure how it happened.

Matt Frohlich, a friend of Kenney, described him as a talented jumper who had traveled around the world.
