ANCHORAGE, Alaska (AP) — A ski guide who was critically injured when he was buried by an avalanche in Alaska has died.

Alaska State Troopers say they were notified by the state medical examiner’s office that 31-year-old Aaron Karitis of Bend, Ore., was declared dead Monday night. He was injured Saturday morning in Kicking Horse Valley west of Haines.

Troopers say Karitis was unconscious when he was pulled out from under the snow.

Karitis was a guide with Southeast Alaska Backcountry Skiing Adventures.

Troopers say the avalanche occurred shortly after Karitis finished checking conditions downslope from his clients. Troopers say the guide didn’t like the conditions and wanted to move.

None of his clients got caught in the avalanche.

Karitis was wearing a locator beacon, which is how rescuers were able to find him

“He was all about adventure,” Jeremy Nelson, the owner of Skjeersaa’s Ski Shop in Bend, said of his friend.

“He had a company he started that was adventure travel. From surf travel trips to fishing trips to skiing trips, Aaron lived his life fully, the way most of us should be able to do, but he definitely did for sure.”
