Sinkhole swallows pond, There
was something missing when Mark Korb went outside Sunday morning. Most
notably, the giant pond that had once been in his yard, which was now a
gaping crater in the ground. The Newcastle, Calif., man says the manmade
pond on his property fell into a sinkhole that sucked it up in a matter
of hours. The speed at which the underground cavity devoured the pond
was staggering.
Korb noted, by contrast, for instance, that when he drained the pond years ago with a pump the process took seven days. A geology professor from nearby Sierra College attributed the sinkhole to old mining activity or a preexisting fracture rather than groundwater dissolving material.
