Out in the Cold - S2.E16

When MacGyver and Pete go skiing, a man switches poles with MacGyver, only moments before being gunned down and killed by his former friends. But the gunshot starts an avalanche, which covers MacGyver completely, leaving it up to Pete to convince the mountain rangers to stage a search and rescue before the next avalanche comes. As MacGyver finally is dug up, the gangsters are there, waiting for him, and whatever is hidden in that ski pole.
