Fortune) <br /> <br />The guard rails along CR 306 kept much of the larger rocks and tree debris banked up on the road, <br />and allowed tile debris to flow downhill on the highway. Therefore, there was debris along a one.mlle <br />stretch of the roadway. To give some perspective, spotter said that a rock and mudslide of this <br />magnitude has never occurred al his place (built in 1970). <br /> <br />On CR 162 (see map). west or the MI.

He got out 01 his truck but left a passenger in the vehide, <br />which then tumbled down into the creek bed. Fortunately, she survived. There are other flow and slide <br />areas upval1ey between the dip and an area called Alpine.
