That is correct, where the day started out great with just fog, then the temperature inversion, then the severe drop. I have pics of that day but none of when we met you guys near the tracks. Josh had never been to the Rock Pile, or even above treeline before, and it made his day to bag Washington in winter. The link to the pictures is here. We'll have to hike together again sometime, the Tri's hike was a great time as well.
