The ice was surprising. The air was not too cold — daytime temperatures were probably mid 50s at the 10,000 foot level where the ice formed. Overnight, the temperature was certainly below freezing. But we didn't see the ice on the hike up (or at least didn't notice it), only on the way down, mid to late afternoon. It was in deep shade. I'm guessing that the temperature of the flowing water was close to freezing (coming from higher elevation and averaging the daytime high and night time low). The very dry conditions might have allowed for some evaporative cooling that caused the water temperature to drop a bit further. And maybe there was some radiant cooling to the sky through the thin atmosphere at altitude. It looks like the ice might have been forming by riming — condensation from vapor to form ice.
