"Megafires" are becoming the norm according to some experts on forest fires. The management of the forests have contributed to the increase in the fire load in many areas of the United States. The Rim Fire burning in and around Yosemite National Park has charred over 222,000 acres and is now 40% contained. 4995 workers are involved in the fire suppression activities. The fire began 15 days ago and full containment is expected to take another 20 days.
