“During the rapid growth of the Park Fire over the last two days, the fire spread quickly through the Ishi Wilderness in the Lassen National Forest,” a CalFire update states. “The cooler temperatures this morning moderated the fire behavior, allowing fire crews the opportunity to actively combat the fire outside of the National Forest lands. This proactive approach aims to safeguard the communities and ecological and cultural resources that may be at risk from the fire.”
