When not in AK, Jim can be found guiding tourers and cat skiers at Snowbird, Utah in addition to being an AAIRE and AAI Instructor.

"Jamie was such an enthusiastic new guide, so eager to learn everything he could, that i couldn’t resist giving him my heli seat now and then to help him to get some experience guiding in the Chugach. He then become one of Doug Coombs’ favorite side kicks in the mountains. Doug always appreciated having an enthusiastic new guide along with him, both to help and to learn as they guided clients together. I think what Doug enjoyed the most about Jamie, as i did, was his humor."
