The bluestones at Stonehenge were identified as coming from the Preseli hills in Pembrokeshire in 1923, by Welsh geologist Henry Herbert Thomas.

In contrast to the 1980s, when land movement in the Flying Triangle landslide area destroyed multiple homes there, the resident-run community association in charge of maintaining much of the gated city has only recently retained a geologist.

Meanwhile, the Rancho Palos Verdes city geologist reported earlier this month that “creep movement” up to 0.7 inches per week has been recorded in Rolling Hills, specifically around Cinchring and Quail Ridge roads, affecting multiple properties — including Bellis’ home.

The big question — and concern — about this creeping in Rolling Hills is whether it might be linked to the devastating movement downhill around Palos Verdes Drive South, where land moved, on average, about 8 inches a week this last month, according to the geologist.

“Based on review of GPS monitoring data shared by Rolling Hills and recent field mapping, the upper limit of the new movement in Rolling Hills appears to cross upper Altamira Canyon,” the geologist wrote in his report.
