Here's a very good map from InciWeb showing the spread of the Rim Fire day by day, from Aug 17 to yesterday, Aug 26. As you can see, the rate of growth has slowed considerably. AP reports this morning that the fire is 20 percent contained, up from 15 percent on Monday. Officials said the fire has grown to about 280 square miles, up from about 252 square miles the previous day, but back burning by crews was responsible for at least part of that increase. The fire is currently the seventh largest in state history, having consumed more than 179,000 acres.
