Rider buried near Cooke City, close call

We received a call (from a third party) about a snowmobiler that was buried with their head 5 feet below the snow and their foot sticking out of the snow. Their partners saw the foot and dug them out. The riders face was blue, but quickly became responsive after a "chest thump". We are unsure of the exact location, but sounds like in the Wolverine/Mt. Abundance area.
