i was northbound i 5 in northern cal. corning was 15 miles ahead and i noticed two perfict holes aprox, 1 mile across one right next too the other with bluegreen, or aquagreen mist seamed to be poring down around the rim of both holes, i stoped at the corning rest area to get a better look. now i coulid get a good look than i noticed somthing elce in the north but i could not see what it was . i needed a pair of binoculrs. thats when i saw dark triangles in groups of 3 and 5 suddlnly pop into view and emeaditly somthing that looked like wispy silky clouds started to pour out the edgdes of all the triangles and in just a few seconds all you could see was just 3 or 5 fluffy clouds this went on for four hrs.
