This figure shows a view of the landslides along Highway 18 that connects Redlands to Big Bear in the San Bernardino Mountains. The strong shaking also caused landslides to occur along Highway 38. The steep slopes are white in color because of the white decomposed granite soil. Big boulders were embedded in the soil covered slopes. The dust clouds created by the landslides were similar to smoke clouds from forest fires. People thought that forest fires were occurring. Image Credit: Lindie Brewer.
