The first four people thought this image was various things, dust storm, smoke, clouds.Susan got really elaborate (thank goodness we have no Anti-Aircraft fire to photograph here) but was wrong too.
Then Myrna nailed it 100% it is a reflection in water!
I can give Sharon 80% it is a reflection but not in a lake.
Lisa gets 60% for getting it basically right and then talking herself out of it!
Here it is a reflection not in a lake but in a puddle!
This puddle is about the two feet across and about 1" deep.I can see I am going to have to really dig into the archive to find some thing you cannot guess
