In High Altitude Central Oregon, You May Expect Mid- Summer, Overnight Frost!

“Cold out! Feels like winter! Where are we, that it should get this cold? We must be at a high altitude. I look out of the sleeping bag and this time see frost on the motorcycle. On the chrome of the gas tank it’s sparkling in the early sunlight. On the black frame where the sunlight hits it it’s partly turned to beads of water that will soon run down to the wheel. It’s too cold to lie around.” (Cont. Next)

5.8 Miles North of La Pine, OR. Not only the dust, but as you see in my photos, I ALSO experienced FROST when I camped at the "Corral Springs National Forest Campground". This was 2 miles West of OR Rt. 97 about 50 miles South of La Pine. In a desert, the atmosphere is totally free of moisture, making it very transparent to infrared (radiant heat). Thus there is rapid transfer of any heat to outer space. This results in rapid cooling to the point of freezing! In desert regions, prior to refrigerators, this was a common way to make ice! You have to see it to believe it!
