Geo 730: June 18, Day 534: Netting the Rock

Looking across the highway to the outcrop, you can see what looks like a vague haze over most of the outcrop. This is roughly the equivalent of hurricane fencing, and helps prevent smaller to moderate rockfalls from reaching the pavement. With larger falls, well, not so much. If you click through to that article, you can see that that outcrop, along the Sandy River near the Columbia River Gorge, had also been screened, but when the boulders are the size of trucks, the netting is just not strong enough to help.
