Where was it -23?

Sorry, on a previous thread I did say where. North central CO, east slope of the Rockies, 7,600 ft. I knew that familyop knew that so I didn't repeat it.

You're really up in the jetstream at 9,200, familyop. I'm surprised it wasn't colder still. The mountains are quirky though. The creases and folds create micro-climates that make conditions better or worse than the overall situation.
