This figure shows the ground cracking near Aberdeen on State Highway 247. A portion of this highway, the main north - south traffic artery through Johnson Valley, Landers, Flamingo Heights, and Yucca Valley was closed to through traffic. The surface faulting reportedly interrupted the ten mile section of State Highway 247. Road cracks, some described as 30 feet long, a foot deep, and measuring 1 to 2 feet wide, made travel impossible in some sections of the roadway. Motorists were reported stranded in the more severely buckled sections. The Lander's postmaster reported that the intensity of the shaking in the Landers earthquake appeared to be strongest near this highway. Image Credit: Lindie Brewer.
