The 4th Pinnacle goes through pretty easily, but it has more of a Southern aspect than the others, making the cruxes melt out before the rest.
Be especially careful of the lower crux, you can hike down if the snow has melted, but no one wants to do that.
From the South side of Argentina, go about a half mile South on the ridge.
This is also the next wide open bowl South of the 3rd Pinnacle, or the 3rd you will cross while heading South.
Ski for about 600 feet to the first crux, which should just be a quick hop.
Get through the gut and rock outcrops and in another 100 feet, you'll come to the bottom constriction.
Heading skier's left is a decent idea if it looks thin, but just take your time.
Ski down to the Bridger return track and back to Bridger Bowl.
