Most of the burned slopes face away from the 60 Freeway. Nearly all of the burned area is charged and aimed downhill towards Gilman Springs Road. "It's all watershed," Cal Fire-Riverside County Chief John R. Hawkins said Tuesday afternoon, standing next to the eastbound 60 before he went into the burned area. "The dirt all runs downhill if it rains, if we have a heavy rain. Asked whether there is concern for erosion impacting the 60, Hawkins looked at the burned slopes facing the freeway and did not hesitate. "Oh there's a risk here, there's a risk of dirt coming down off the hill here, absolutely there's a risk," Hawkins said. "Here the watershed is pretty short, where it can make its run and move dirt, but it can be very dangerous." Hawkins took a shovel with him and used it for balance on the steep, unstable slopes. When he returned, Hawkins remarked on erosion already evident on the black hillsides. "This is dry erosion, which is just the weight coming down the hill, pushing the dirt," Hawkins said. "You take that dry erosion and you couple it with moisture, it lubricates the granules of dirt and the hillside can come down." The cause of the Gilman Fire remained under investigation on Tuesday, a Cal Fire spokeswoman said. Suppression costs were determined to be $479,000, Cheri Patterson of Cal Fire-Riverside County said.
