Has anyone here ever recorded 10F degrees in August? Last August I actually did while camping high in the Beartooth Mountains of Montana.
My diary quotes the following:
The last night was the most incredibly cold summer night I had ever spent. The temperature dropped to an almost unbelievable 10F (-12C) and all of our water bottles froze solid. Since our elevation was lower than previous nights, I presume that the cold air sinks off the mountains and pools into this meadow. In fact, this night at least tied the coldest temperature at a camp I have ever recorded anytime between April 17 and October 25. I stayed warm throughout the night, but Kessler got cold and we put his parka on in the middle of the night. A porcupine and skunk (?) kept me up much of the night.
Below is the photograph I took of the frozen waterbottle:
If you want to see photos of what the terrain looks like, there are some below:

Even though it was up in the mountains, I still found it amazing that the temperature dropped to 10F on an August 28!
It seems the area we were camping in that night forms a cold air sink, sink none of the other nights were close to that cold. It was interesting, if a bit chilly, at least it was chilly for August.
