Large (or should we say "long"?) cloud over the San Gabriel Mountains, seen from Falcon Ridge Town Center in Fontana, California, U.S.A. Actually, this cloud was receding when this photo was taken; it had been covering the top of the mountain range like a blanket the previous morning (probably dropping snow) and provided a spectacular view from the bottom of Cajon Pass on I-15 (northbound). Unfortunately, I was in the driver's seat at the time and couldn't switch drivers so there is no picture of that. In other words, this is sort of an aftermath of the "blanket cloud phenomenon" (just my own words, "not" a scientific term). Still, it's amazing to see a cloud behave this way.
