NDOT has temporarily closed US 50 in the Cave Rock area on Lake Tahoe’s east shore, after five more boulders fell onto the road. Several times this week, boulders about the size of cars fell from a roadside slope onto eastbound travel lanes. No vehicles were involved in the slides, and no injuries are reported. The rocks fell near Logan Creek Drive north of Cave Rock. Large boulders remain perched on the destabilized roadside slope, and the temporary road closure is a safety precaution.
