Not that it matters a lot, but was this really October? There’s a distinct lack of snow and ice on those mountains.

The only exception to this of course is evaporative cooling. Moving air can cool a wet surface even if the temperature of the air is above the surface temperature.
That originally what I though this question was asking but it turns out it’s just an instrument problem.

For those out of the loop this effect is called “hoar frost” pronounced exactly like you would think and yes, it’s hilarious every time.
My spouse and I make sure to mispronounce it like Frank in Always Sunny.

I mean, yes past the Viking villages in Canada but not past the Vikings in North America. Those went into the 1400s.
