Paul’s Slide. Left: Air photo taken May 27, 2017, one of many that Beth Haddon will analyze with structure-from-motion software to measure changes in ground elevation. Right: Caltrans employees and contractors use an excavator and bulldozer to remove Paul’s Slide debris from California State Highway 1. Note recent construction of concrete and a line of grouted reinforcing bars (“nails”) to slow undercutting of southbound lane. Photo taken June 6, 2017, by Kevin Schmidt.
