The fires in California, sparked by lightening from late June storms, continue to burn as of mid-July. Earth Observatory has an image from July 13, 2008 showing the current state of some of the fires.
This image was captured by the MODIS on the Aqua satellite on July 11, 2008. In it, the fires in northern California are giving off a great deal of smoke, which is being blown out over the Pacific Ocean - and over Nevada in the east. Each red dot represents an active fire.
Lake Tahoe, located on the border of California and Nevada, right where California bends, is almost completely obscured by smoke. Near it is the American River Complex Fire. North of that, is the Cub Complex Fire, and towards the west is the Yolla Bolly Complex fire. North of the Yolla Bolly Complex are the Lim, Whiskeytown, Alps, Ukonom, and Siskiyou Complex fires. The Earth Observatory page we linked to has a labeled image.
