Authorities say the body of a 36-year-old Idaho Falls man missing since he was caught in an avalanche Wednesday afternoon was found Thursday morning.

The Fremont County Sheriff's Office said Adam Wayne Andersen's body was found within a couple of minutes after search and rescue crews brought in a search dog from Teton County, Wyo.

The sheriff's office said emergency workers received a report at 5 p.m. Wednesday that a snowmobile rider was caught in an avalanche near Mount Jefferson in the Centennial Mountains of Island Park. Other people snowmobiling with him tried to find the man but were unsuccessful, as were members of the Fremont County Search and Rescue organization.

The search was called off Wednesday evening because of poor snow conditions, the weather and the length of time that had passed since the avalanche.
