Not the normal double rainbow, the colors aren't reversed.
Also the red is there but yellow and blue are not distinct on the upper
one. And, I have never seen a rainbow with the peak pointing earthward!
Are you sure this isn't a lens artifact?

Every time I ski Squaw I get hurt. We got so much snow that tens of thousands of trees around the cabin are bent over or broken. Mo names all our trees, and now we call this one Bender. https://dl.dropboxusercontent.com/u/53724080/Truckee/PCD_2017/Bender.JPG I think it will straighten out on its own, but she wants me to get ropes and straps and gadgets to pull it upright.

Where did it all go, 20 meters of snow takes a long time to melt, unless it's extra warm.

I can remember ice cold temps and lots of snow and ice on Big Bear in the middle of July when the temp down on the desert floor was 120oF. At the summit, where it got 800", there's still a lot. Lower down, it's been warm and most is melted. There's not much snow left below 6000 feet. The rivers are raging still. The Truckee is usually knee-deep and runs at a walking pace. https://dl.dropboxusercontent.com/u/53724080/Truckee/PCD_2017/Truckee_River_1.JPG Oroville Dam got whacked by lots of snow followed by a rapid thaw. Maybe next year we can have our global warming and perpetual drought back. -- John Larkin Highland Technology, Inc picosecond timing precision measurement jlarkin att highlandtechnology dott com http://www.highlandtechnology.com

Well, nice to have someone with more knowledge, I went 800 deep in a
google image search on rainbows, nothing at all like Larkin's picture.

I don't think it is a rainbow, it's a snowbow. The arc is produced by the angle of the sun, yourself and the nature of the prism producing the "bow". With a rainbow the sun is behind you and the arc is produced as part of a circle around the axis extending from the sun through you toward the rainbow. In this case I believe the sun was just above the picture and the two bows were parts of circles around the sun. Clearly the prismatic effect in the ice crystals was different from what happens in rain drops. -- Rick C

Ice crystals with the right prismatic shape and winds to align them... http://www.atoptics.co.uk/halo/supinf.htm Playing around with halosim will get you a match. -- Regards, Martin Brown
