A Green River man is in critical condition after an ATV crash. Sweetwater County Sheriff's Detective Dick Blust said the crash occurred around 8 Sunday night.

Riding 12 miles from town:

"Seventy-three-year-old year-old Carl Morck was out alone with his four-wheeler in the western slopes of White Mountain in the Scott Canyon area on Sunday, September 25. At around 8:00 pm he lost control of the ATV and crashed."

Det. Blust said that Morck activated a PLB, Personal Locator Beacon, which uses satellite positioning to send a distress signal.

Distress transponder:

"In this instance, the signal was picked up by the United States Air Force’s Rescue Coordination Center at Tyndall Air Force Base in Florida. The Center then began relaying the coordinates by phone to the Sheriff’s Office Communications Center in Green River."

Rescuers arrived the following morning, found the crash scene, found Morck's backpack a half mile away, but didn't find Morck.

Walking injured:

"In spite his injuries, Mr. Morck kept moving, trying to get out on his own, though it would have been better had he remained at the scene of the crash."

Morck was later found about four miles from the ATV.

Victim's condition:

"He was transported by emergency helicopter to the University of Utah Medical Center in Salt Lake City, Utah with internal injuries, where he is listed, as of yesterday (Tuesday), in critical condition."

The search was conducted by Sweetwater County Search and Rescue volunteers Cpt. Chris Schutz and Eric Schillie, plus dog team handlers Joyce Fett and Jackie Nix. The mishap is under investigation.
