How was the climbing overall?
Pic 4 looks boot top deep and cold wintery snowpack-ish.
And it looks like the N couloir, not that I've been in it.

Also, the road is open to the bathroom with limited parking but how is the road in general?

Congrats on your ride & summit (?).

Sorry I havent been much of a story teller in the past years. Yes the south facing approach was nice and frozen over, after dropping over the saddle the snow had more of a winter pow form. It was deep boot packing up the north couloir to the final ridge pitch. The ridge pitch has snow all the way to summit, and is a steep ish little section. Crampons, and axe were used. Two split boarders and one skier rode from the summit. The boot pack back out wasnt as bad as expected. They should be getting new snow tonight as well. There were 1-2 very small wind effected sections that we took caution climbing. After the turnoff, road is 4x4. I saw Subarus parked at the turnoff, and a rav4 outhouse section. I suppose it depends how much you like your car but Id recommend 4x4.

For the info

Potosi N Couloir was one of my favorite snow climbs. Such a cool, aesthetic line. And even better you got to snowboard it!
