CHEYENNE, Wyo. (Associated Press) - Bobby Model, a noted adventure photographer who suffered a traumatic brain injury more than two years ago in South Africa when a chunk of concrete smashed through the windshield of his car, died Wednesday. He was 36.

Model died at West Park Hospital in Cody after a brief illness, said Sharon Miller, Model's photo assistant. The cause of death of wasn't immediately available.

Model's work appeared in National Geographic, Outside, The New York Times and other publications. His assignments took him from the rivers of Burundi in search of a fabled man-eating crocodile to climbing the Nameless Tower of northern Pakistan, one of the world's largest granite walls.

Model moved to Nairobi, Kenya, in 2004 to better position himself to cover Africa, according to a biography on his Web site. Model's sister, Faith Model, was driving Bobby when the incident happened in Cape Town, South Africa, in June 2007.

Model was working on a National Geographic photo essay documenting the Baltistan region of Pakistan, site of a border dispute with India, around the time of his injury.

Model landed his first major photography assignment in 1995 when he accompanied renowned rock climber Todd Skinner to the Nameless Tower in northern Pakistan. National Geographic helped fund the journey, on which Model shot memorable images of the granite spire.
