"We knew that there were some potential unstable rocks in the area, so we sent some Forest Service geologists in to have a look," said Rachel Pawlitz, public affairs officer for the Columbia River Gorge National Scenic Area. "What we learned is that there's an overhanging rock that is unstable."
"So there is a solution for it. We can have a contractor come in and do rock scaling, which is where they intentionally cause it to fracture and fall in a somewhat controlled way so that it's no longer hanging there leaving us with uncertainty about it," she said.
